Mid- and far-IR Spectra of the acid and Some deuterated acids in various physical States were also investigated and all of the observed Bands were interpreted in terms of a hydrogen-bonded Cyclic dimer. The only exception was the vapor at about 100掳 which Showed a Spectrum for Monomeric ...
The infrared (IR) spectrum (KBr) of 1 revealed the characteristic absorptions of esters (vmax 1730 cmÀ1), amide (vmax 1670 cmÀ1), hydroxyl, and/or amide NH (vmax 3400 cmÀ1) groups. Its molecular formula was established as C13H21NO7S (m/z [M-H]À 334.0960, +0.2 mmu) by...

The complexation-induced changes in the FTIR-ATR spectrum of IBP have been interpreted by comparison with the theoretical vibrational wavenumbers and IR intensities of dimeric structures of IBP, derived from symmetric hydrogen bonding of the two carboxylic groups, computed by using Density Functional ...
