- W2049687680 abstract "Abstract Raman spectra of the gaseous, liquid and crystalline states have been recorded for HCOOCH3, DCOOCH3 and HCOOCD3. The vibrational data for methyl formate are consistent with acis-planar skeletal structure and there is no evidence for a secondgauche ortrans conformation. A vibrational analysis for HCOOCH3 based upon depolarization measurements, relative band intensities and positions, in addition to isotopic shift ratios, is briefly outlined. The vibrational assignment has been correlated with previous i.r. studies and is consistent with product rule calculations. An assigmnent for the 1 ← 0 methyl torsional transition for each of the respective isotopes is based upon difference tones observed in the low frequency Raman spectra of the liquid state. The magnitude of the internal rotational barrier for the methyl group is 1.22, 1.13 and 1.11 kcal/ mole for thed0,d1 andd3 compounds. A value of 68.8 kcal/mole is calculated forV* for the C O torsion by using the observed Raman line at 338 cm−1 and microwave structural parameters. The magnitude and nature of the C O torsional barrier is discussed in detail." @default.
