Heat capacity and normal modes of poly (L‐valine) in relation to spectra of oligovalines

Phonon Dispersion and Heat Capacity in Microbial Poly(ε-L-lysine)(M-ε-PL)

“…It is calculated at 1528 cm À1 and assigned to the peak observed at 1540/1523 cm À1 (IR/Raman). 14 This agrees well with the amide II modes in other sheet structures such as -PLV, -PALS, -PG I and -PLS [20][21][22][23] [ Table IV]. Amide III is a combination of N-H in plane bend and C-N stretch as in amide II but in opposite phase.…”

“…The structural parameters thus obtained are given in Table I. Initially the force constants were transferred from poly("-caprolactone) (PCL), 19 poly(L-valine) 20 and poly(-L-lysine) 16 and later modified to give the ''best fit'' to the observed spectra of Maeda et al…”
