## Abstract The study of the ^1^H and ^13^C resonance spectra of a series of 13 photochromic pyranocarbazoles was carried out using two‐dimensional methods. ^1^H and ^13^C resonances were deduced from the concerted application of HSQC, HMBC and DEPT experiments. Copyright © 2001 John Wiley & Sons,

✦ Synopsis
Abstract
The complete ^1^H and ^13^C NMR assignment of a series of imidazobenzoxazines by a combination of one‐ and two‐dimensional experiments (COSY, HSQC and HMBC) is studied. Moreover, 2D NOESY and 1D selective NOESY are reported. This procedure allows the identification of the regioisomers obtained. Copyright © 2010 John Wiley & Sons, Ltd.
