摘要: It is suggested that the low‐temperature paramagnetism of many aromatic free‐radical solids may be due to triplet excitons, and formation these exciton states rather than other magnetic crystal lattice structures favor a singlet pairing electrons on neighboring molecules. As an example it shown paramagnetic resonance spectra certain TCNQ charge‐transfer complexes observed by Chesnut Phillips interpreted in terms excitons.
