A two-step photoionization scheme is used to determine vibrational frequencies of the n = 3 Rydberg states of triatomic hydrogen. Symmetric-stretch frequencies in orthotrihydrogen of 3212.1 and 3168 cm/sup -1/ are measured for the N = 1 levels of the states 3s /sup 2/A/sup '//sub 1/ and 3d /sup 2/E'', respectively. Transitions to bending-mode excited levels in the 3d states and overtone levels of the 3p /sup 2/ E' state are observed also.
