Infrared radio-frequency double resonance of (13)CH(3)OH
Abstract:
Infrared radio-frequency double-resonance spectroscopy has been carried out for (13)CH(3)OH. Four K-type doublet transitions have been observed below 1 GHz, using the 9P(10) and 9P(12) CO(2) laser lines. The results confirm previously proposed assignments of infrared absorption transitions and far-infrared laser emission lines observed in this molecule. Measurements of the A-state splittings have permitted the determination of the asymmetry splitting parameters S(O)(K) and S(CO)(K) for (n, K) = (0, 4) and (1, 3).

IR Absorption Frequency: Hybridization
Among the sp, sp2, and sp3 hybridized orbitals, sp orbitals have the maximum s character (50%). Consequently, the electrons are held more closely to the nucleus, resulting in stronger and shorter C–H bonds that stretch at a...
