Abstract
The unique high spectral resolution resulting from application of nonl inear polarisation spectroscopy in the frequency domain at 77 K direct ly reveals 6 subbands (at 649, 657, 667, 672, 675 and 679 nm) in the c hlorophyll a/b Q(y)-region of trimeric light-harvesting complex II. A shortening (from about 90 to 35 fs) of the corresponding dephasing tim es towards the 'blue' edge of the Q(y)-band was observed. (C) 1997 Els evier Science B.V.
