H. Ishikawa et al., Observation of the highly excited vibrational levels of HCP: Application of IR-UV-SEP triple resonance spectroscopy, CHEM LETT, (9), 1999, pp. 941-942
Highly excited vibrational levels of HCP involving both CH stretch and bend
modes excitation, vibrational energy of which is 15600 - 17000 cm(-1), in
the ground electronic state were observed by IR-UV double resonance pumped
dispersed fluorescence and stimulated emission pumping spectroscopies.
