A simple pulse sequence for selective excitation in Fourier transform NMR

A pulse-repetition rate set to q = 2np radians, i.e., Dfn = n/t, where q = degrees, n = an integer, f = frequency, and t = sec, provides, for a very narrow band of frequencies near the q = 2np conditions, a magnetization vector in which the steps caused by pulses outweigh those caused by precession and which induces a max. NMR signal which is close to the pure absorption-mode condition. Selective excitation by this simple pulse sequence was illustrated by added multiplet subspectra in the Fourier transform 13C NMR of Me2C:CHNMe2. [on SciFinder (R)]
