Zusammenfassung:. The 35 Cl nuclear quadrupole resonance (NQR) frequency (ν Q ), NQR spin–lattice relaxation time ( T 1Q ), 1 H nuclear magnetic resonance (NMR) second moment ( M 2 ), and NMR spin–lattice relaxation time ( T 1 ) were measured for chlorodiazepoxide as a function of temperature. The hindered rotation of two dynamically nonequivalent methyl groups in two different chlorodiazepoxide molecules and the phenyl ring was detected. The relevant physical parameters of these motions were determined.
