✦ Synopsis

The polarized phosphorescence spectra of 1,s naphthyridine and 1,s naphthyridine-& in duene and durenedtq mtied crystals have been observed at 4°K. The emitting triplet state is assigned 3B,( rr,rr*). In theory, the assignment of the lowest singlet n,n* state on be determined from a consideration of the triplet radiative lifetime, but for L,5 naphthyridine the result is ambiguous.
