Аннотация

The submillimeter-wave spectra of the arsine molecule in the excited vibrational states (0100) and (0001) have been investigated for both allowed R branches (J + 1 ← J, K ← K) and weak-intensity "forbidden" Q branches (K = 3 ← 1, 3 ← 0, 2 ← 0). Weak "forbidden" transitions of the AsH3 molecule in the (0001) state can be observed due to the increase of sensitivity of a RAD-spectrometer by using quasi-optical cavity absorption cells. As a results of joint analysis of new submillimeter recordings together with the known infrared, microwave, and radiofrequency data, the set of spectroscopic parameters obtained allows one to describe all the available spectroscopic data for the (0100) and (0001) vibrational states of the AsH3 molecule within experimental uncertainties.
