A -- RESEARCH AND DEVELOPMENT SOL 52SBNB9C1056 DUE 071299 POC Marsha Rodgers (301)975-6398, FAX 301-963-7732 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 negotiate on a sole source basis with Dr. David A. McWhorter, Charlottesville, Virginia, under the authority of 41 U.S.C. 253c(1) -- Only one responsible source for research and development services. Services shall include (1) building, maintaining and developing a transient far-infrared (THz) 1 KHz laser spectrometer, (2) helping to modify, maintain and develop time-resolved hydrogen-bonding experiments using an infrared picosecond/femtosecond laser and infrared focal plane array detection system; (3) collecting and analyzing data obtained from the above instruments; (4) aid in publication and dissemination of results, and (5) preparation of monthly reports on experimental studies for a Competence Project entitled: "Advanced Terahertz Metrologies" performed in the NIST Physics Laboratory. This program entails advanced laser spectroscopic studies of the far-infrared spectroscopy of model DNA and protein systems and monitoring their time-dependent spectral changed associated with low-frequency motions. F.O.B. Destination, Gaithersburg, Maryland. Period of Performance is two years from date of award. Deliverables shall be twenty-four monthly reports. All work shall be performed at the NIST, Gaithersburg, Maryland site. This is a sole source because Dr. McWhorter is uniquely qualified to perform this requirement due to his established experimental and theoretical expertise in the study of low frequency molecular vibrations and is a recognized expert on the vibrational dynamics of gas phase molecules in their ground electronic state. He is now extending his expertise toward studying vibrational excitations of molecules in solution and has applied his requisite experimental and theoretical talents to understanding their microscopic behavior to compare to earlier gas phase work. Dr. McWhorter has also 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 experimentally obtained ultrafast transient ultraviolet/visable and infrared spectra. 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. Posted 06/02/99 (W-SN338182). (0153)
