## Abstract The ^1^H NMR spectrum of naphtho [1β²,2β²:4,5]thieno[2,3β__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
