Abstract:

The high-resolution electronic-vibrational-rotational spectrum of the 2A' → 2A''electronic transition of the H2O radical in the region 1.22-1.27 μm was studied. The spectrum was obtained by the method of intracavity laser spectroscopy. The spectrum was calculated using Polo's formulas for slightly asymmetric prolate tops. Analysis of the spectra yielded accurate values for the rotational constants of the 2A'(001) and 2A'(020) states and the vibrational frequencies n2 and n3 of the A~2A' state . It was established that the forbidden ΔK = 0 transitions occur. A possible mechanism (Coriolis interaction of the close-lying 2A'(001) and 2A'(010) levels) explaining their appearance is proposed. It is shown based on calculations that vibrationally excited HO2 radicals are formed in the 2A" (010) state via the reaction СН3О+O2→ СН2O+НО2.
