35Cl NQR measurements were carried out on a series of chlorobenzenes with the 1,1,3,3-tetramethylguanidinyl substituent {TMG = -N=C[N(CH,)&}. The substituent constants up, a,,, , a, and aR for the TMG group were estimated from the relationships between the NQR resonance frequencies, vQ , and substi
