Abstract
A study, using NMR techniques, of the propensity of complex formation of silver ions with hydrocarbons and heterocyclic compounds containing nitrogen, oxygen and sulphur is described. The results are compared with similar data using 1,3,5βtrinitrobenzene as an acceptor. The differences in the two sets of data are interpreted in terms of localized and delocalized interactions in the formation of weak complexes.

The Raman spectra of Meisenheimer complexes derived from 1,3,5trinitrobenzene and proline, tryptophan, albumin and pyrrolidine were obtained. The spectra excited in and out of resonance with the electronic transition at ca. 460 nm show an outstanding enhancement of modes involving mainly the symmetr
## Abstract In this communication we present the first stable zwitterionic spirocyclic Meisenheimer compound based on an NβN rearrangement in the reaction between picric acid and diisopropylcarbodiimide. The structure was confirmed by singleβcrystal Xβray diffraction. Furthermore, this compound exh
Toxic effects of 1,3,5-trinitrobenzene (TNB) in male and female rats were evaluated by feeding powdered certified laboratory chow diet supplemented with varied concentrations of TNB (0, 50, 200, 400, 800 and 1200mg kg-' diet) for 14 days. Food intake by female rats in 400, 800 and 1200mg TNB diet gr
