Resonance Raman spectra have been obained from various iodine solutions. High intensity overtone progressions of the stretching vibration were observed, allowing the determination of the spectroscopy constants ω e and ω e x e and estimation of ω e y e for the stretching vibration for the ground state in various environments. The values are compared to those obtained for the gas phase. The overtone progression shows a large increase in half‐bandwidth with increasing vibrational quantum number.
