“…Before long, I was the faculty member in charge of the spectrometer, the NMR technician, and the NMR operator for the department. I worked together with Richard Kula and Donald Sawyer on the NMR of metal complexes of ethylenediaminetetraacetic acid (EDTA), methyliminodiacetic acid (MIDA), and nitrilotriacetic acid (NTA) (19), and with Marty Schweizer and George Helmkamp on the NMR of purines (87). Oscar Paez started to prepare concentrated alkali metal liquid ammonia solutions, and we determined the microwave skin depth of these metal solutions by EPR to estimate the electrical conductivity (11).…”

“…While at Harvard, I had many conversations with Professor John Baldeschwieler on 19 F NMR relaxation. It was apparent that spinrotation coupling was an important relaxation process for 19 F. It turned out that this was the case for 13 …”

“…In this molecule, the barrier to internal rotation of the −CF 3 group is sixfold; sixfold barriers are typically very small, a few calories per mole. 19 F was chosen because the rotational magnetic fields per unit angular momentum experienced by the three 19 F nuclei in the −CF 3 top were expected to be large. Alan, together with Tom Burke, built a pulse NMR machine to measure the 19 F NMR longitudinal relaxation rates (1/T 1 ) in benzotrifluoride and hexafluorobutyne-2 (10, 33).…”

The 19 F T 1 s were short; moreover, part of the NMR relaxation was observed to be independent of the viscosity of the medium, as expected for spin-internal-rotation coupling.…”

NMR of base-stacking interactions in nucleic acids in solution, dynamic structure of bilayer membranes, membrane biophysics, metal cofactor structure and function, redox linkage and proton pumping in cytochrome c oxidase, methane hydroxylation by the particulate methane monooxygenase, early kinetic events in protein folding AbstractDespite growing up amid humble surroundings, I ended up receiving an excellent education at the University of California at Berkeley and postdoctoral training at Harvard. My academic career at Caltech was shaped by serendipity, inspirational colleagues, and a stimulating research environment, as well as smart, motivated students and postdocs who were willing to join my search for molecular understanding of complex biological systems. From chemical physics I allowed my research to evolve, beginning with the application of NMR to investigate the base stacking of nucleic acid bases in solution, the dynamic structure of membranes, and culminating with the use of various forms of spectroscopy to elucidate the structure and function of membrane proteins and the early kinetic events in protein folding. The journey was a biased random walk driven by my own intellectual curiosity and instincts and by the pace at which I learned biochemistry from my students and postdocs, my colleagues, and the literature and through osmosis during seminars and scientific meetings.

New compounds of the Mo(VI)2O7H3(Am)ntype (where HAm=glycine, DL-alamine, DLMethionine, or L-Leucine) were obtained from an acidic aqueous solution (pH= 1) containing sodium molybdate and amino acid. These compounds seem to be isostructural with each other, and all are diamagnetic. Their infrared spectra show characteristic v(Mo=O) bands.The ethylenediaminetetraacetato chelates of molybdenum(VI) and (V) have already been stud-
