Abstract
Fourier transform spectra of oxirane (ethylene oxide, c-C2H4O) have been recorded in the 3.17 μm - 3.5 μm region with a resolution of 0.005 cm-1. In addition, a Raman spectrum covering the same spectral region was recorded at a resolution of 0.44 cm-1. Using the Raman spectrum, it was possible to determine rather precisely, the band center of the ν1 band. This was essential to assign the infrared region transitions of the B-type ν1 band since this rather weak band is masked by the much stronger ν9 A-type band and ν13 C-type band falling in the same spectral region. Using a Watson-type Hamiltonian, it was possible to reproduce the observed energy levels reasonably well and the Raman spectrum could be satisfactorily modeled. The band center was determined to be ν0 (ν1) = 3018.3456(10) cm-1.Citation
