Several techniques have been used to measure the dipole moments of 6 vibrational states of HCN. Conventional molecular beam electric resonance spectroscopy can readily observe the ground state and the 010 and 020 excited bending modes. A high temperature supersonic nozzle beam source was used to make MBER measurements on the 001 state, the C-N stretch. Infrared laser excitation of the molecular beam gave access to the 100 state (C-H stretch). The same laser was used in a gas phase RF-IR double resonance experiment to study the 110 state. These data will be discussed in terms of the dipole moment function of HCN.
