Beginning with a review of early spectrometers, this article describes the essential features common to instruments for spectroscopic and imaging applications. Evolution of spectrometers and spectroscopic techniques have been closely linked, and thes

Two different sampling schemes for quadrature detection are in common use. In the first, data from both channels are sampled simultaneously at regular intervals. In the second, the data are sampled alternately from each channel. While both sampling s

The observation of chemically induced dynamic nuclear polarization (CIDNP) in 13 C Fourier transform NMR spectra taken during the photolysis of cyclic ketones is direct evidence for the intermediacy of biradicals. Cycloheptanone showed the strongest

Heteronuclear decoupling with Chirp modulation in conjunction with 180°-phase alternation is demonstrated to be a more efficient decoupling method than 180°-phase alternation alone. A theory that predicts the results of Chirp modulation alone is de

Dipole‐dipole interactions between protons in a glucopyranose derivative have been studied by means of the nuclear Overhauser effect and by spin‐lattice relaxation experiments. The Overhauser enhancement measurements utilize a new pulse technique

Carbon-13 Fourier transform NMR spectra are reported which exhibit gross discrepancies in signal amplitude and phase that vary in a cyclic manner as a function of the frequency offset from resonance. These anomalies occur when the interval between pu
