Difficulties are described which are encountered in NMR spectroscopy when attempting to invert simultaneously several multiplets that comprise transitions which share common energy levels. These problems turn out to be due to the undesirable excitation of ...
This paper reports on single quantum well characterization by means of luminescence excited with a laser (photoluminescence) and an electron beam (cathodoluminescence) at liquid helium temperatures. Small quantum well regions with smaller confinement were ...
It is shown by simulation and expt. that frequency-modulated "chirp" pulses are very effective for exciting multiple-quantum coherences over large bandwidths. Chirp pulses can be considered as an alternative to composite pulses to combat the effects of l ...
The optical properties of low pressure metal organic vapor deposition grown GaAs/AlxGa1-xAs (x = 0.5) single quantum well structures (SQW) with grown-in dislocations (GD) were studied by low temperature cathodoluminescence (CL) and photoluminescence (PL). ...
It is shown by simulation and expt. that selective pulses designed to invert or excite magnetization over a limited frequency window induce significant phase shifts over a bandwidth much larger than the chosen window. These phase shifts affect all expts. w ...
Frequency-modulated chirp pulses, for exciting multiple-quantum coherences over large bandwidths, can be considered as an alternative to composite pulses to combat the effects of large offsets and tilted effective fields. Refocusing of the phase dispersion ...

The photoelectron spectra of 3-endo-(2), of 3-exo-methoxybicyclo[2.2.1]heptan-2-one (3) and of 2-endo,3-endo-dimethoxybicyclo[2.2.1]heptane (4) are analyzed in comparison with data reported for other analogous systems and with predictions based on quantum ...
