WebMolecular weight distributions in high-conversion polymerizations are not nearly as predictable as those in low-conversion reactions, and they will vary with the particular monomer and polymerization conditions. A number of factors combine to make high conversion molecular weight distributions broader than those calculated in Section 8.14.1. WebMar 16, 2024 · Raman spectroscopy is an alternative way to get information about the infrared transitions within a molecule. In order for a vibrational transition to be Raman active, the molecule must undergo a change in polarizability during the vibration. Polarizability refers to the ease of distorting electrons from their original position.
