摘要：

Thermal and IR induced interconversions between several forms of methanol dimers trapped in solid nitrogen have been reexamined by means of FTIR spectroscopy. Use of a pass band filter transmitting in the 1200-500 cm-1 domain allows identification of a highly unstable form, not observed in the previous works. Temperature effects and selective photoconversions upon excitation of CO stretching modes with CO2 laser lines enable the barrier heights involved in the conversions between two groups of conformers to be estimated.
