Proton and carbon magnetic resonance spectra of Lewisite or dichloro( trans ‐2‐chlorovinyl)arsine have been measured and the results are compared with the n.m.r. spectral parameters of other trans ‐1,2‐substituted ethylenes. The coupling constants can be rationalized by substituent electronegativity. The chemical shifts show an unusually large paramagnetic effect from the AsCl 2 group.
