✦ Synopsis

Vibrational dipole matrix elements and radiative transition probabilities have been evaluated from electric dipole moment functions for the X'Z + states of CH+ and CD+, which were calculated from highly correlated electronic wavefunctions. The dipole moments in u=O amount to 1.679 D (CH+) and 1.313 D (CD+), respectively. In comparison to other molecular ions the infrared transition probabilities are found to be rather small. For instance, the Einstein coefficient of spontaneous emission Ah amounts to 1.63 s -' (CH+ ) and 0.19 s-' (CD+ ) . Dipole moment functions of the neutral CH species in the X 'II and a "2states have also been calculated and are compared with previous theoretical functions.
