Abstract

The ^1^H and ^13^C NMR spectra of d‐biotin were observed at 400 and 100 MHz, respectively. Various types of two‐dimensional NMR spectroscopy were performed to assign the spectra. The previous assignment of ^13^C NMR spectrum of d‐biotin reported by Bradbury and Johnson was modified, and the dihedral angles between the CH bonds of the ring were determined. The populations of the conformers produced by internal rotation around the C‐2C‐δ bond were estimated.

COSY and NOESY spectra (400 MHz) have been used to complete the assignment of the 'H NMR spectra of 1and 3-nitrobenzo[e]pyrene. Both compounds show strong bay region nuclear Overhauser enhancement and significant coupling across bay regions. Both compounds also exhibit extensive long-range couplings

The total assignment of the 13C and the ' H NMR spectra of four derivatives of 1,3diaza-2,4-diboranaphthalene has been performed. The interpretation of the spectra was achieved from the concerted application of direct and long-range heteronuclear chemical shift correlation and homonuclear COSY two-d

## Abstract Following earlier studies on the development of one‐ and two‐dimensional NMR methods based on selection of coherences via maximum‐quantum pathways and using inverse ^1^H detection, a pulse sequence is now described for analogous direct heteronuclear detection for use in laboratories whi
