Observation of electric-quadrupole infrared transitions in water vapor
Molecular absorption of infrared radiation is generally due to rovibrational electric-dipole transitions. Electric-quadrupole transitions may still occur, but they are typically a million times weaker than electric-dipole transitions, rendering their observation extremely challenging. In polyatomic...
