Effects of modification of molecular structure on Raman spectral depolarization ratios: aqueous betaine (CH3)3NCH2CO2 center dot 29D2O versus (CH3)4NBr center dot 29D2O

Spinner, Ernest

Description

Replacement of a CH in (CH3)4N+ by a CO2- group raises ρ from 0.012 to 0.034 for symmetric N-C stretching and from ca. 0.026 to 0.031 for all-in-phase methyl C-H stretching. ρ for antisymmetric C-H stretching and CH3 bending remains in the 0.73-0.75 ran
