The important dental material referred to as 6-[(4-vinylbenzyl)propylamino]-1,3,5-traizine-2,4-dithione (VBATDT), which may have the thione-thiol tautomerization, was confirmed for the first time to have the dithione structure in the solid state by using ¹³C CP/MAS NMR with the dipolar dephasing technique. VBATDT was also shown to have the dithione structure in acetone solution by comparison of the ¹³C NMR spectrum with the corresponding solid state spectrum.
