## Abstract ^15^N n.m.r. spectra of [^13^C‐2, 3‐^15^N~2~‐__guanidino__]arginine and [^13^C, ^15^N~2~] urea were obtained in D~2~O and H~2~O at a variety of pH values both with and without proton decoupling. The effects of the proton exchange rate are readily observable in the proton coupled ^15^N s

## Abstract The small negative magnetogyric ratio (Ξ³) of the ^15^N nucleus decreases the efficiency of ^15^Nο£Ώ^1^H dipole‐dipole relaxation to about 25% of that for an analogous ^13^C nucleus. This may lead to greater competition from other relaxation mechanisms in ^15^N n.m.r. and consequent partia

Derivatives of methyl 2-amino-2-deoxy-cr-D-altropyranoside-2-1siV and methyl 3-amino-3-deoxy-a-D-glucopyranoside-3-'s~ have been synthesized by addition of phthalimide-15N to methyl 2,3-anhydro-4,6-O-benzylidene-a-D-allopyranoside. The structures of the phthalimido derivatives that resulted have be
