Polarizability ofCO2studied in molecular-beam laser Stark spectroscopy

Abstract

The polarizability of the ${\mathrm{CO}}_2$ molecule in excited vibrational states has been studied using molecular-beam laser Stark spectroscopy techniques. The analysis yields the polarizability anisotropies Δα=2.215(7) A${̊}^3$ for the 00°1 state, 2.244(7) A${̊}^3$ for the 02°0 state, and the difference of the isotropic polarizabilities (${\alpha }_{00°1}$-${\alpha }_{02°0}$)=-0.0124(8) A${\mathrm{̊}}^3$. .AE
