LASER-MICROWAVE DOUBLE RESONANCE LASER SPECTROSCOPY OF ALKALINE EARTH MONOHALIDES: HYPERFINE STRUCTURE AND ELECTRIC DIPOLE MOMENTS IN GROUND AND EXCITED STATES

Abstract

Microwave-optical polarization sepctroscopy (MOPS) and molecular beam laser-microwave double resonance techniques have been applied to calcium, strontium and barium monohalides. The precise determination of hyperfine parameters and electric dipole moments provided information about intramolecular fields, field gradients and the charge density distribution which are compared with the results of different bonding models and ab initio calculations.
