Ultraviolet irradiation of matrix‐isolated formamide ( 1 ) in solid argon with light of wavelength 248 nm leads to the formation of formimidic acid ( 2 ). Comparison of the experimental IR spectrum of the photoproduct with the calculated IR spectrum of 2 shows clearly that two rotamers 2a and 2b are formed.
