Abstract: | The results of investigations into the high-resolution Fourier spectrum of the AsH3 molecule first registered in the range 9720–9900 cm–1 with a resolution of 0.015 cm–1 are given in the present paper. Lines of (500; A1) and (500; E) bands are interpreted by the method of combination differences. The spectroscopic constants of the examined arsine bands are determined by solving the inverse problem. They have allowed 98 rotational energy levels (with Jmax = 6) to be reproduced with errors close to the experimental ones. |
