Cyanamide vapor was condensed at 12 K with HF in excess argon producing a 1:l complex of the form H,NCN--HF. The HF submolecule stretching fundamental was observed at 3458 cm-', and the HF librational modes appeared at 694 and 686 cm-I, which are very similar to the HF modes observed for the CH,CN--HF complex. Several perturbed submolecule modes of cyanamide in the 1:l complex were identified; large perturbations for the CEN stretch at 2306 cm-' and ...
