A -- RESEARCH AND DEVELOPMENT SOL 52SBNB8C1117 DUE 080298 POC Sandra L. Febach, Contracting Officer, (301) 975-6326, Romena R. Moy, Contract Specialist, (301) 975-4999 WEB: NIST Contracts Homepage, http://www.nist.gov/admin/od/contract/contract.htm. E-MAIL: NIST Contracts Office, Contract@nist.gov. The National Institute of Standards and Technology (NIST) intends to enter into a sole-source contract with Dr. Todd A. Heimer of Laurel, Maryland under the authority of 41 U.S.C. 253(c)(1) -- Only one responsible source. This procurement is for the setup, maintenance, execution, data collection, data analysis and publication of ultrafast laser spectroscopic experiments on studies of "Time-Resolved Laser Spectroscopy of Catalytic Polymerization Reactions" performed in the NIST Physics Laboratory. This program entails performing advanced laser spectroscopic studies of photo-initialized polymerization reactions using complex metallocene catalysts in homogeneous solution phase. Additionally, this requirement involves performing related investigations of organometallic dye sensitizers on semiconducting supports, examining photoreactions of organometallic species, and determining reaction rates and energetics of these systems as well as identify unknown transient species during reaction. The primary focus will include: (1) study of photoinitiated catalyst activation and dynamics leading to transient molecular catalyst-polymer precursors during homogeneous liquid-phase polymerization reactions, and (2) developing experimental and analytical techniques to study electron transfer and molecular re-arrangement dynamics for dye-sensitized semiconductor nanoparticles and homogeneous organometallic photochemical reactions. Dr. Heimer is uniquely qualified to perform this requirement due to his established experimental and theoretical expertise in the study of photoinduced molecular dynamics, catalysis and electronic processes in various material phases including liquids, liquid-surface, and solid phases. Dr. Heimer also has demonstrated a complete up-to-date understanding of nanosecond, picosecond, and femtosecond lasers, pulsed laser spectroscopy, nonlinear optics, software/hardware development and its implementation for multichannel infrared spectroscopic data acquisition, and the ability to analyze experimentallyobtained ultrafast transient ultraviolet/visible and infrared spectra. Deliverables shall be twelve monthly reports. All work shall be performed at the NIST Gaithersburg, MD site. The period of performance shall be one year from contract award with a one 1-year option. This notice is not a request for competitive proposals. Written responses shall contain sufficient documentation to establish a bonafide capability to fulfill the requirement. A solicitation is not available. See Numbered Notes 22 and 26. (0169)
