摘要:
The vibrational spectra of HCOF and of DCOF have been examined in the gas and solid phases by infrared techniques and in the liquid phase through the Raman effect. Of the six expected fundamentals for a molecule of point group C8, frequencies have been assigned to the five planar vibrations and a tentative assignment made for the nonplanar vibration. A normal coordinate analysis was applied to the A′ vibrations of HCOF, neglecting all interaction terms, and a set of force constants obtained which predict reasonably well the isotopic shifts in DCOF.
