Title: A Physiochemical Approach to the Study of the Primary Acts in Photo-biological Processes

Abstract

This project about as a result of a request made by the Atomic Energy Commission to the Chemistry Dept. at the University of Minnesota to provide opportunities for training biological scientists in on-the-job research operations of a significant nature in physical chemistry. The object of the program was to make a small contribution towards the improvement of research and teaching in biological sciences through the incorporation of more and sounder physical chemistry.

  • Our study targets recent (Plio-Pleistocene) faults and young (Tertiary) petroleum fields in southern California. Faults include the Refugio Fault in the Transverse Ranges, the Ellwood Fault in the Santa Barbara Channel, and most recently the Newport- Inglewood in the Los Angeles Basin. Subsurface core and tubing scale samples, outcrop samples, well logs, reservoir properties, pore pressures, fluid compositions, and published structural-seismic sections have been used to characterize the tectonic/diagenetic history of the faults. As part of the effort to understand the diagenetic processes within these fault zones, we have studied analogous processes of rapid carbonate precipitation (scaling) in petroleum reservoirmore » tubing and manmade tunnels. From this, we have identified geochemical signatures in carbonate that characterize rapid CO2 degassing. These data provide constraints for finite element models that predict fluid pressures, multiphase flow patterns, rates and patterns of deformation, subsurface temperatures and heat flow, and geochemistry associated with large fault systems.« less

    Efforts directed toward development-of a pulsed x ray source for use in studying primary processes and intermediates in photochemical reactions are described. The field emission principle is planned for the x ray tube to obtain large pulsed currents from a heated cathode of W filaments surrounding a cylindrical target anode. Material to be studied is mounted inside the anode chamber, which is open to the atmosphere, and optical measurements are made along the axis of the anode. The elements associated with the anode and cathode were tested for thermal and electrical stability and final assembly of the tube is planned.more » (J.R.D.)« less

    The use of lasers in determining the Raman and resonance Raman spectra of stable chemical and biological systems has produced many important and useful structural results over the past decade. The use of picosecond lasers and vidicon detection in Raman spectroscopy has greatly assisted in the development of resolved techniques. The high intensity of the laser made it possible to obtain Raman spectra with the laser frequencies within the absorption band of the substance studied. In the present work we present the resonance Raman spectra of bacteriorhodopsin transients in the 30 to 50 psec time scale of two vibrational regionsmore » of retinal, one (1100 to 1400 cm/sup -1/, the fingerprint region) is sensitive to retinal conformational changes and the other (approx. 1646 cm/sup -1/) is of the protonated C=N stretching vibration of the Schiff base.« less
