Extinction coeffeicient needed!
« on: November 03, 2007, 02:55:56 PM »
Hi all!
Please can someone help me! I need the extinction coefficient of meso-tetra(4-sulfonatophenyl) porphyrin. I desperately need it by Monday.

Dear Olliebee,

Sorry!, But have you already thought about:
      -   In what Solvent?
      -   By which “pH”?
      -   In which purity degree?
And maybe:
      -   Which Complex?

SORRY!  I don’t know it anyway!, and I believe not many (any?) will …..

Hoping anyway somebody may know “anything”.

Good Luck!
