We have measured the frequency shift of the 817 cm−1 bend mode of as a function of temperature by infrared absorption spectroscopy. The phase relaxation of the bend mode is dominated by low energy excitation of 270±9 cm−1 modes. Further lifetime measurements by transient bleaching spectroscopy are necessary to elucidate the decay mechanism.
