FTIR difference spectroscopic studies of M intermediate and LA bacteriorhodopsin in the O‐H stretching region show bands at 3671 and 3641 cm −1 , respectively. The O‐H stretching bands in this region may reflect protonation‐deprotonation changes or environmental change in the tyrosine residues in bR.
