The circular dichroisna spectra in rhodopsin and bathorltodopsin are theoreti-cally analysed in terms of intrinsic optical activity of the retinal chronaophoreaccording to a torsion model proposed in paper I. The self-consistent HMOmethod is used to treat the m-electron systena of the chro?nophore. From theanalysis of the ct- and /j-bands of optical absorption and circular dichroisn'n spectra,the plausible conforncation of the chromophore is predicted as follows. In rho-dopsin, 6s-cis, 11-cis protonated retinal Schiff-base 11215 12s-trans foruaa and thebonds 6C-7C, IIC-]2C and 12C-]3C are twisted in -, -4- and - directions,respectively, when torsional angles 0's are naeasured clockwise froxaa planar cisconformation. Although we cannot deter?aaine the valtues of 0's definitely, theranges of them are 05 7 = -40'? -120', 0..-..=30'x40'and 0..-.3=-130'N -15O'. In bathorhodopsin, tlae bond IIC-J2C is isonaerized to a lratzs formby the rotation of about 100' -120' around it in the plus direction.
