Transient spectra of the styryl dye DCM (4-dicyanomethylene-2-methyl-6-p-dimethylaminostyryl-4H-pyran) in methanol were studied by the pump-supercontinuum probe technique with 40 fs time resolution. A theory of measurements with a supercontinuum probe is presented. Gain and absorption spectra were m
