Rotational analysis of bands of the B—X system of gaseous AgCl

Abstract

The rotational analysis of eight bands of the B—X system (ν_e= 31602.7 cm^–1) of ¹⁰⁷Ag³⁵Cl has been obtained, using separated ¹⁰⁷Ag and Cl in natural abundance. The 0—0 band of ¹⁰⁷Ag³⁷Cl has also been analyzed. The results for the ground state are in satisfactory agreement with those obtained from the microwave spectrum. The upper state has the character of a O⁺ state, and the internuclear distance r_e is 2.317 Å. A short extrapolation of the band origins leads to a value for a dissociation limit corresponding to a potential maximum in B O⁺ at about 95.8 kcal mole^–1 above v= 0 in X¹Σ⁺.
