Abstract
Several hitherto unknown thiazolo[3,2‐a]quinolinium salts derivatives were prepared and characterized. Two‐dimensional high field nmr methods were employed to make complete assignments of the proton and carbon nmr spectra for these compounds.

1H and 13C NMR spectroscopic data of both the quinolinium ring and the spacers for 32 symmetrical bisquinolinium compounds were assigned by a combination of one- and two-dimensional experiments (DEPT, HMBC, HMQC). The compounds have electron-releasing groups at position 4 of the quinolinium ring, wi
