✦ Synopsis
Tune-resolved fluorescence spectroscopy of poly (N-vmy I carbazolc) rn tetrahydrofuran solutton has revealed the presence of three cmtttmg spccres, namely a normal excrmer emtttmg at hmw = 420 nm. a hrghcr-energy excrmer sate at A,, = 370 nm whrch mtcrconrcrts \ tth the "normal" stte. and a thud spectes whtch emtts at 370 nm but not at 420 nm. and \ htch does not convert to the normal excrmer The tdenttty of thrs specms, and the kinrttcs of fluorescence of the polymer. are dtscussed
