The nature of the chromophore configuration of metarhodopsin II (meta II) has been a subject of recent controversy. Earlier resonance Raman results from this laboratory had indicated that meta II has an unprotonated Schiff base linkage between the chromophore and apoprotein. It has been argued, on the other hand, that the Raman evidence does not exclude a non‐covalently bound retinal chromophore. In this communication we present additional evidence and further arguments in favor of our earlier conclusion regarding the state of the chromophore in meta II.
