Analysis of The Hyperfine Structure of The Maser Transition JKa, Kc = 61, 6 − 52, 3 of A Molecule H2O

Year: 2025

Type: conference-paper

Abstract: The values of the spin-rotation and spin-spin interaction constants were improved by applying the quantum mechanical approach to measurements of the hyperfine-split transition frequencies in H2O (JKa, Kc = 61, 6 – 52, 3). Possible line profiles of the H2O molecule were calculated for both the maser and purely thermal cases, based on the solution of the radiative transfer equation for different values of optical thickness and inhomogeneous line widths of the super.ne components. Comparisons of the calculated results with observations of the narrowest profiles of the H2O maser lines are presented using the RT-22 PRAO ASC FIAN.
