Vibrational analysis of the beta system of (BO)-B-10-O-18

Ten bands of the system (B(2)Sigma(+)- X(2)Sigma(+)) of the (BO)-B-10-O-18 molecule have been observed for the first time. The spectrum was obtained by emission spectroscopy from a low-pressure arc, at medium dispersion, and vibrationally analyzed using isotope shift measurements. Vibrational analysis gave the constants omega(e) and omega(e)x(e) for both electronic states involved in the transitions
