Calcium monohydride is an astronomically important molecule. Despite the long history of work on this molecule, discrepancies still exist between experiment and theory for the higher vibrational levels of the B/B'(2)Sigma(+) state. We report on rotational-vibrational-electronic transitions to the B/B'(2)Sigma(+) state which we have assigned to the B/B'(2)Sigma(+) (v = 9, 10, 11 and 18) - X-2 Sigma(+) (v = 0) transitions. The energy spacing of the higher lying vibrational levels of the B/B'(2)Sigma(+) state alternates strongly with vibrational quantum number as predicted by the coupledchannel calculations of Carlsund-Levin et al. (2002). We confirm that this alternation extends all the way from v = 9 to v = 20.
