Abstract

We report a new laser spectroscopic technique capable of detecting weak state-state interactions in diatomic molecules. Specifically, a weak interaction has been observed between the $6psigma$ antibonding orbital of the CsXe (B $^2Sigma^+_{frac{1}{2}}$) state and a $5dsigma$ MO associated with a $5dLambda$ ($Lambda = 0, 1$) state. Thermal Cs-rare gas collision pairs are photoexcited by a circularly-polarized optical field having a wavelength within the B $^2Sigma^+_{frac{1}{2}} longleftarrow$ X $^2Sigma^+_{frac{1}{2}}$ (free$longleftarrow$free) continuum. Subsequent dissociation of the B $^2Sigma^+_{frac{1}{2}}$ transient diatomic selectively populates the $F= 4, 5$ hyperfine levels of the Cs 6p $^2$P$_{frac{3}{2}}$ state, and circularly-polarized ($sigma^+$) amplified spontaneous emission (ASE) is generated on the Cs D$_2$ line. The dependence of Cs 6p spin polarization on the Cs(6p)-Xe internuclear separation ($R$), clearly shows an interaction between the CsXe(B $^2Sigma^+_{frac{1}{2}}$) state and a $5dLambda$ ($Lambda = 0, 1$) potential of the diatomic molecule.
