Femtosecond free induction decay of cobalt–phthalocyanine in pyridine and of octaethyl porphine in pyridine was observed by use of a white-light interferometer with a resolution time of 6 fs. Also, frequency-domain complex optical constants of the samples were obtained by Fourier-transform analysis of the phase-sensitive interferograms.
