Abstract

We have investigated the use of ^13^C for the detection of saturation transfer difference (STD) NMR spectra. By detecting the STD spectrum in the ^13^C channel it is possible to eliminate the residual water signal in the STD‐NMR spectrum. We have employed an INEPT transfer in order to shift the magnetization from the proton channel to ^13^C. As a sample system to check our method we have used human serum albumin and phenylalanine. We have shown that such a transfer can be accomplished and gives reasonable signal intensities. Copyright © 2009 John Wiley & Sons, Ltd.

## Abstract ^13^C NMR chemical shifts and ^13^C–^19^F and ^13^C–^1^H coupling constants are reported for 103 halocarbons. Methods used for analyzing complex spectra (e.g. simultaneous ^1^H and ^19^F broadband decoupling, 2D INADEQUATE/FRED, HMQC, 35,37Cl isotope effects) are briefly illustrated. Lo
