Theoretical Evaluation of Atomic Polarizations of Diatomic Molecules

摘要

The atomic polarizations,PA(theor.), of five diatomic molecules, HCl, DCl, HBr, NO, and CO, have been calculated from an equation derived from dispersion theory (Van Vleck, 1927), using recent data obtained from infrared dispersion and absorption intensity measurements. ThesePA(theor.) values are compared with thePA(exp.) values obtained from dielectric constant and optical refractive index measurements. The greater accuracy of thePA(theor.) values is emphasized. ThePA(theor.) values have been used to recalculate the dipole moments, mgr;, of the diatomic molecules considered. A qualitative relationship is discussed between the series ofdmgr;/drand mgr; values for some of the diatomic molecules. ThePA(theor.) are calculated approximately for the gaseous alkali halides.
