Rotational profiles of vibrational bands recorded at the B31(53P1) ← X10+(51S0) transition in CdAr complex

Analysis of profiles of ( υ ′; υ ″ = 0) vibrational bands, ( υ ′ = 0,1,2,4,5), recorded with partly resolved rotational structure using the B 3 1(5 3 P 1 ) ← X 1 0 + (5 1 S 0 ) transition in CdAr is presented. The analysis allowed for determination of the B v ′ and D v ′ rotational constants, and new values of ω e ′ vibrational frequency and D e ′ well depth of the B 3 1-state interatomic potential. The new characterization of the B 3 1 state in CdAr is closer to the result of recent ab initio calculations [Chem. Phys. Lett. 471 (2009) 29] than results of our previous study performed with vibrational resolution [Spectrochim. Acta A 56 (2000) 1613].
