# Optical absorption spectrum of Protoporphyrin IX dimethyl ester in chloroform # # Data from PhotochemCAD 2.1a has been munged on 2 June 2017 by Scott Prahl to make # the information available to non-Windows users. Although I have tried to be as careful # as possible, I may have introduced some error; the cautious user is advised to compare # these results with the original sources at www.photochemcad.com: # # H.

Taniguchi and J. S. Lindsey "PhotochemCAD 2. A refined program with accompanying # spectral databases for photochemical calculations", Photochem. Photobiol., 81, 212-213, 2005. # # The spectral absorption measurements were made by M. Taniguchi on 10-03-2004 using a HP 8453. #The absorption values were collected using a spectral bandwidth of 1.0 nm. # # These measurements were scaled to make the molar extinction coefficient match # the value of 171000 cm-1/M at 407.0 nm. These values were # then interpolated to report extinction coefficients at regular 1nm intervals # # The reported molar extinction coefficient is from # Falk, J. E. (1964) Porphyrins and metalloporphyrins, p. 232, Elsevier, Amsterdam. # ##Wavelength (nm) Molar Extinction (cm-1/M) 300 10101 301 9977 302 9901 303 9806 304 9753 305 9757 306 9769 307 9779 308 9830 309 9868 310 9976 311 10083 312 10185 313 10351 314 10485 315 10668 316 10867 317 11090 318 11329 319 11576 320 11863 321 12155 322 12454 323 12776 324 13110 325 13469 326 13843 327 14190 328 14559 329 14931 330 15283 331 15649 332 15989 333 16334 334 16681 335 17035 336 17385 337 17748 338 18114 339 18506 340 18939 341 19361 342 19847 343 20385 344 20947 345 21586 346 22259 347 22954 348 23719 349 24564 350 25449 351 26366 352 27350 353 28337 354 29353 355 30428 356 31498 357 32627 358 33661 359 34879 360 36110 361 37451 362 38738 363 40129 364 41521 365 42891 366 44536 367 46534 368 48747 369 51069 370 53282 371 55384 372 57454 373 59610 374 61788 375 64129 376 66539 377 69028 378 71625 379 74119 380 76418 381 79032 382 81532 383 84232 384 86665 385 89219 386 91897 387 94615 388 97469 389 100212 390 103048 391 106345 392 109908 393 113569 394 117126 395 121207 396 125402 397 130242 398 135524 399 140160 400 144748 401 149667 402 154455 403 159227 404 163381 405 167174 406 169865 407 170999 408 171940 409 171632 410 169606 411 166607 412 162474 413 157177 414 150672 415 143607 416 135550 417 127353 418 119074 419 110511 420 102091 421 93818 422 86265 423 79413 424 72546 425 65965 426 60013 427 54044 428 48871 429 43949 430 39459 431 35791 432 32321 433 28768 434 25706 435 23189 436 20683 437 18539 438 16634 439 14912 440 13394 441 11961 442 10794 443 9745 444 8793 445 7967 446 7232 447 6607 448 6058 449 5566 450 5146 451 4800 452 4478 453 4148 454 3910 455 3745 456 3546 457 3372 458 3231 459 3099 460 2994 461 2882 462 2805 463 2741 464 2741 465 2715 466 2663 467 2655 468 2646 469 2653 470 2702 471 2815 472 2914 473 2991 474 3058 475 3142 476 3270 477 3355 478 3444 479 3490 480 3644 481 3755 482 3849 483 3978 484 4115 485 4422 486 4749 487 4774 488 5027 489 5487 490 5904 491 6312 492 6820 493 7369 494 7893 495 8364 496 9055 497 9608 498 10299 499 10967 500 11603 501 12218 502 12886 503 13449 504 13863 505 14110 506 14234 507 14190 508 14079 509 13838 510 13524 511 13086 512 12526 513 11931 514 11231 515 10489 516 9696 517 8793 518 7950 519 7045 520 6290 521 5624 522 5105 523 4640 524 4386 525 4250 526 4242 527 4354 528 4640 529 4943 530 5400 531 5974 532 6565 533 7339 534 7997 535 8730 536 9409 537 10064 538 10686 539 11188 540 11481 541 11673 542 11704 543 11555 544 11136 545 10560 546 9674 547 8676 548 7681 549 6696 550 5756 551 4947 552 4253 553 3707 554 3300 555 2936 556 2683 557 2467 558 2412 559 2357 560 2403 561 2409 562 2516 563 2700 564 2855 565 3066 566 3341 567 3641 568 4025 569 4422 570 4891 571 5358 572 5794 573 6188 574 6566 575 6737 576 6798 577 6776 578 6610 579 6374 580 6179 581 5986 582 5727 583 5437 584 5191 585 4939 586 4593 587 4246 588 3926 589 3535 590 3184 591 2836 592 2524 593 2245 594 1971 595 1758 596 1588 597 1450 598 1383 599 1316 600 1285 601 1269 602 1255 603 1251 604 1250 605 1226 606 1180 607 1115 608 1062 609 1007 610 1004 611 969 612 938 613 987 614 1011 615 1103 616 1212 617 1339 618 1479 619 1642 620 1890 621 2070 622 2368 623 2677 624 3021 625 3427 626 3809 627 4218 628 4600 629 4886 630 5121 631 5186 632 5125 633 4866 634 4483 635 3946 636 3354 637 2721 638 2125 639 1612 640 1220 641 895 642 641 643 475 644 301 645 245 646 94 647 48 648 11 649 -44 650 -89 651 -128 652 -142 653 -155 654 -202 655 -63 656 31 657 -793 658 -467 659 -197 660 -190 661 -148 662 -162 663 -147 664 -155 665 -134 666 -100 667 -182 668 -135 669 -124 670 -145 671 -161 672 -158 673 -197 674 -191 675 -182 676 -180 677 -214 678 -210 679 -239 680 -232 681 -258 682 -273 683 -260 684 -261 685 -255 686 -293 687 -288 688 -309 689 -298 690 -293 691 -308 692 -303 693 -304 694 -325 695 -326 696 -309 697 -308 698 -329 699 -353 700 -340 701 -336 702 -345 703 -339 704 -343 705 -347 706 -347 707 -325 708 -335 709 -339 710 -338 711 -336 712 -345 713 -349 714 -343 715 -352 716 -350 717 -345 718 -340 719 -356 720 -339 721 -343 722 -354 723 -359 724 -357 725 -340 726 -348 727 -365 728 -361 729 -351 730 -354 731 -343 732 -357 733 -375 734 -352 735 -366 736 -370 737 -391 738 -392 739 -377 740 -381 741 -377 742 -373 743 -366 744 -392 745 -374 746 -380 747 -377 748 -387 749 -392 750 -378 751 -399 752 -388 753 -398 754 -384 755 -399 756 -394 757 -381 758 -384 759 -418 760 -393 761 -399 762 -425 763 -418 764 -395 765 -395 766 -420 767 -428 768 -400 769 -374 770 -413 771 -418 772 -434 773 -415 774 -424 775 -418 776 -429 777 -412 778 -393 779 -425 780 -422 781 -410 782 -405 783 -419 784 -413 785 -432 786 -435 787 -406 788 -414 789 -419 790 -442 791 -430 792 -421 793 -414 794 -422 795 -399 796 -434 797 -429 798 -409 799 -421 800 -427
