We are trying to determine Lewis and Bronsted acidity of ZSM5 using pyridine and collidine.
I would like to know
1. How to determine integrated molar extinsion coefficient (IMEC) for pyridine
2. How to determine integrated molar extinsion coefficient for collidine
3. Can I use directly integrated molar extinsion coefficient for pyridine reported in literature to determine Lewis and Bronsted acidity
