Abstract
^1^H NMR of the tricyclic molecule 3 โ Cyano โ1,2,2โ trimethyl โ 6 โ azatricyclo โ[3.3.1.0^3,8^]nonโ6โene does not permit the distinction between this structure and the other regioisomer that can be formed in a photochemically induced reaction. The elucidation of the structure was possible via the assignment of the ^1^H and ^13^C NMR spectra of this compound obtained using twoโdimensional NMR spectroscopy.

## Abstract The ^1^H NMR spectrum of naphtho [1โฒ,2โฒ:4,5]thieno[2,3โ__c__]quinoline is highly congested because all the protons are in an aromatic environment, and the structure of the molecule is nearly symmetric. With this in mind, the assignment of the ^1^H and ^13^C NMR spectra of this compound
The total assignment of the 13C and the ' H NMR spectra of four derivatives of 1,3diaza-2,4-diboranaphthalene has been performed.
