dc.description.abstractThe $OC-Br_{2}$ van der Waals complex was observed in a 5''-pulsed-slit free jet expansion. The complex was detected by the IR absorption in the vicinity of 1-0 vibrational transition of C-O. Four isotopic progressions were recorded in the spectra. The rotational structure was consistent with a linear $OC-Br_{2}$. The spectra were well-fitted by semirigid-rotor linear molecule model, the rotational constants for $OC-Br_{2}^{79}, OC-Br^{79}Br^{81}, OC-Br^{81}Br^{79}$ and $OC-Br_{2}^{81}$ isotopomers were obtained. The band origins of $OC-Br_{2}$ were found to be 2152.83836(17), 2152.83929(16), 2152.84117(15) and $2152.84209(13) cm^{-1}$ for the isotopomers of $OC-Br^{79}, OC-Br^{79}Br^{81}, OC-Br^{81}Br^{79}$ and $OC-Br_{2}^{81}$, respectively. From the isotope substituted rotational constants, the distances of the centers-of-mass of CO and $Br_{2}$ were calculated to be 4.864 {\AA} and 4.875 {\AA} for the excited and ground state, respectively. The van der Waals bond formation siginficantly perturbed both the CO and $Br_{2}$ bond lengths. In the ground state, the $C-O$ bond of the complex was 0.027 {\AA} shorter than that of the uncomplexed CO, while the Br-Br distance of the complex was 0.037 {\AA} longer than the bond length of free $Br_{2}$.en_US
