| Abstract: | A qualitative analysis of the enolic form of
3-oxo-L-gulofuranolactone (ascorbic acid) has been made by a satisfactory
vibrational band assignment using FTIR and FT Raman spectra. The calculated
theoretical vibrational frequencies are compared with the experimental
frequencies by employing the molecular mechanics method using MM3 force field.
The observed frequencies are used to compute the thermodynamic functions,
namely, the entropy, heat capacity and heats of formation using standard
expressions, at one atmospheric pressure in the 298-398 K temperature range. |
