## Abstract ^1^H and ^13^C NMR data for six pheno‐thiazine derivatives are reported. Spectral assignments were made on the basis of two‐dimensional homonuclear ^1^H,^1^H and heteronuclear ^1^H,^13^C correlation techniques (COSY, COSY‐LR, HETCOR, COLOC) and ^13^C,^1^H coupling constant measurements.

✦ Synopsis
H and 13 C NMR spectroscopic data for 5a-androstanes and halo-5a-androstanes with different substituents at positions C-3, C-9, C-11 and C-17 were examined and assigned by a combination of 1D and 2D NMR experiments. The substituent effects on the 13 C chemical shifts were compared with those of epi-androsterone, used as a reference compound. The coupling constants n J( 19 F, 13 C) were measured for compounds 6, 8, 11 and 14.

1 H and 13 C NMR spectral data for phytochelatin, NH 3 C --Glu-Cys 2 -Gly-COO , were assigned by a combination of one-( 1 H, 13 C) and two-dimensional (DQF-COSY, CH-COSY, HMBC) NMR experiments.
The indole alkaloid strychnobrasiline was studied using one-and two-dimensional NMR techniques. The interpretation of these spectra led to the complete assignments of all carbon and proton chemical shifts.
