The 35Cl NQR frequencies of (Cl3C)3SiCl at 77 K are interrelated with the inverse spin-lattice relaxation times. This interrelation is in the general form described by a hyperbola equation. It is shown that the “crystal effect” can be resolved in

The field constant of the NQR frequency of a chlorine atom (35Cl) in a series of arsenic derivatives [R1R2R3AsCl]+M− was estimated from correlations. The field frequency is ∼41.5±3.5 Hz cm kV−1, which is nearly twice as much as that in analogo
