Abstract:

Critical evaluation of the available experimental data on the frequencies of the rotational and vibrational-rotational transitions of the OH molecule in the ground electronic state Х²P is performed using the Ritz combination principle. The transition frequencies weighted in accordance with the experimental errors have been processed by the RITZ program code. The analysis of the dimensionless weighted deviations made it possible to exclude "bad frequencies" from consideration and to carry out processing with a standard deviation of 1.8. As a result of critical evaluation, a set of 1056 empirical RITZ energy levels is obtained with an appropriate uncertainty for each level. The empirical Ritz energy levels are compared with the calculated levels given in the HITRAN spectroscopic database.

Keywords:
