The 29Si spin-lattice relaxation times, &(%), of the various silicate anions present in high-purity alkaline silicate solutions are reported. Regular silicate cages display the longest T,(29Si) values and, in the case of the cubic octamenc cage, an unexpectedly large nuclear Overhauser enhancement,

## Abstract In order to check our current knowledge on the principles involved in ฮฒโhairpin formation, we have modified the sequence of a 3:5 ฮฒโhairpin forming peptide with two different purposes, first to increase the stability of the formed 3:5 ฮฒโhairpin, and second to convert the 3:5 ฮฒโhairpin i
A fundamental problem in Fourier transform NMR spectroscopy is the calculation of observed resonance amplitudes for a repetitively pulsed sample, as first analyzed by Ernst and Anderson in 1966. Applications include determination of spin-lattice relaxation times (T 1 's) by progressive saturation an
