Calculating The Absorption Population And Maximum Quantum Number Of Electronic States Of Isotopic H1F19 And H2F19 Of Hydrogen Fluoride Molecules

A theoretical calculation has been carried out of some of the spectroscopic properties of isotopic H1F19 and H2F19 Hydrogen fluoride molecules such as the population of the absorption spectrum of electronic transitions X and B as a function of the temperature in the range from 50 to 500 K and values of J in the range of 0 to 20. It was found that the values of calculated spectroscopic properties studied in this paper for H2F19 molecule greater than that of H1F19 molecules and the population of the molecule increase as the temperature increase with increase of J reaching maximum values the decrease reaching maimum values. Besides a calculation is being carried out for determination of the maximum rotational quantum number of the same electronic transitions. The theoretical calculation shows that the value of Jmax increases with the increases in temperature and its values Jmax for the electronic state X greater than that of B as the of the temperature increases
