dc.description.abstractExtensive new spectra have been taken for the visible systems of YOH and YOD, in an attempt to establish the vibrational assignments in the very confused $\bar{B}^{1}\Pi$ and $\widetilde{C}^{1}\Sigma^{+}$ states. It turns out that there is very strong vibronic coupling through the bending vibration between the $\widetilde{C}^{1}\Sigma^{+}$ state and the $A^{\prime}$ (lower) Born-Oppenheimer component of the $\tilde{B}^{1}\Pi$ state. The effect is that the bending frequency of the $\bar{C}^{1}\Sigma^{+}$ state is increased by 50\% relative to the ground state, while that of the $A^{\prime}$ component of the $\widetilde{B}^{1}\Pi$ state is reduced so far that the molecule becomes non-linear, with a potential barrier of about $120 cm^{-1}$ at the linear configuration; the $A^{\prime \prime}$ (upper) component of the $\widetilde{B}^{1}\Pi$ state is not affected. The principal evidence for the barrier is that the 010 $\Sigma^{+}$ vibronic level lies $1.4 cm^{-1}$ below the 000 level (linear molecule notation) in the $\widetilde{B}^{1}\Pi$ state of YOD. The density of the level structure in the $\widetilde{C}^{1}\Sigma^{+}$ state arises partly because higher levels of the $\widetilde{B}^{1}\Pi$ state lying among the levels of the $\widetilde{C}^{1}\Sigma^{+}$ state gain intensity through the vibronic coupling.en_US
