Characterization of protonated formamide-containing clusters by infrared spectroscopy and ab initio calculations: I. O-protonation

Characterization of protonated formamide clusters by vibrational predissociation spectroscopy confirms theoretical predictions that O-protonation occurs in preference to N-protonation in formamide. Results of the work carried out suggest an interesting possibility of C-H...O bond formation in the protonated formamide trimer.
