The 1H and 13C NMR resonances of four 3H-naphtho[2,1-b]pyrans were completely and unambiguously assigned by a combination of homonuclear (gs-COSY), 1H-detected heteronuclear one-bond (gs-HMQC) and long-range (gs-HMBC) gradient-selected correlation experiments.

✦ Synopsis
The effect of 29 commonly encountered substituents on the chemical shifts of ct, 13 and C5H5 positions in monosubstituted ferrocenes are tabulated and employed for determining IH NMR assignments in 1,2-and 1,1'-disubstituted ferrocene derivatives.

The 1 H NMR spectrum of ampicillin in aqueous solution at pD 8 and 4 was assigned using a combination of 2D T-ROESY and 1D GOESY techniques. The Me-˛and Me-ˇchemical shift assignments, determined at pD 8, are opposite to existing literature values obtained under similar conditions. Additionally, the
Assignments of nearly all the 1H chemical shifts of glycogen are made by 2-D 1H-1H homonuclear and 13C-1H heteronuclear COSY. We demonstrated that it is possible to obtain well-resolved 2-D n.m.r. spectra for a large molecule like glycogen. The seven nonequivalent protons of the glucose residues in
Gas-phase 200 MHz 'H NMR spectra of nineteen primary and nine secondary aliphatic amines were obtained at total densities below 0.15 amagat at 148.6 OC. Theoretical predictions of 'H chemical shifts of ammonia and methylamine are compared with the gas-phase experimental values. The amino proton chem
