It is shown that excitation of solutions of 2-naphthaldehyde in either cyclohexane or acetonitrile at 300 K with light of 308-nm wavelength leads in both cases to the formation of two triplet states which have slightly different lifetimes T in the range 250 < T < 350 ns. These triplet states, formed
