Calculating the Normalized Absorption Population and Maximium Quantum Number of Electronic States of Isotopic B11H1 AND B11H2 of Boron Hydride Molecules

Abstract

A calculation has been carried out for the theoretical calculation of some of the spectroscopic properties of isotopic B¹¹H¹ and B¹¹H² Boron Hydride molecules, such as the population of the absorption spectrum of electronic transitions X, A 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 B¹¹H² molecule greater than that of B¹¹H¹ molecule, and the populations of the molecule increase as the temperature increase with increases of J reaching maximum values the decreases reaching minimum values. Besides, at the value of J_max increases with the increase in temperature, and its values (J_max) for the electronic state X  greater than that of A and B as the of the temperature increases. While the values of normalized Boltzmann population of the rotational energy level versus 2B(J+1) at different temperature of B¹¹H¹ higher than that of B¹¹H².
