51. Applications of Ultrafast Transient Infrared Spectroscopies
Published: 5/1/2002
Authors: T Heimer, Edwin J Heilweil
Abstract: Modern techniques for performing ultrafast transient mid-infrared spectroscopy using turnable, broadband infrared probe pulses with multi-channel CCD and infrared focal plane array detection is presented. Novel application of these picosecond and fem ...

55. Ultrafast Terahertz Spectroscopy: Measuring Low-Frequency Vibrational Modes of Hydrogen-Bonded Systems
Published: 7/1/2000
Authors: D A McWhorter, Alan L Migdall, Edwin J Heilweil
Abstract: An ultrafast terahertz spectrometer using ZnTe crystals for optical rectification and free-space electro-optic sampling has been developed to measure vibrational dynamics of biological molecules. Spectrometer characteristics and absorption spectra o ...

56. Electron Injection, Recombination and Halide Oxidation Dynamics at Dye-Sensitized Metal Oxide Interfaces
Published: 5/1/2000
Authors: T Heimer, Edwin J Heilweil, C A Bignozzi, G J Meyer
Abstract: Time-resolved infrared measurements indicate ultrafast, < 350 fs electron injection from (4,4'dcb)^d2^Ru(NCS)^d2^ (1) and (5,5'dcb)^d2^Ru(NCS)^d2^ (2) to nanostructured TiO^d2^ electrodes. {(4,4'dcb) = (4,4'-COOH-2,2'-bipyridine)} Although rapid, t ...

57. Pulsed Terahertz Spectroscopy of DNA, Bovine Serum Albumin and Collagen Between 0.1 and 2.0 THz
Published: 3/1/2000
Authors: A G Markelz, A. E. Roitberg, Edwin J Heilweil
Abstract: We report the first use of pulsed terahertz spectroscopy to examine low frequency collective vibrational modes of biomolecules. Several absorption features were observed for pressed pellets of calf thymus DNA, bovine serum albumin and collagen in th ...

58. Electron Injection, Recombination and Halide Oxidation Dynamics at Dye-sensitized Metal Oxide Interfaces
Published: 1/1/2000
Authors: T A Heimer, Edwin J Heilweil, C A Bignozzi, G J Meyer

59. Growth Inhibition and Transient Temperature Measurement of Laser-Irradiated Hair Fibers and Follicles
Published: 1/1/2000
Authors: L K Iwaki, T Heimer, Edwin J Heilweil, P A Manos
Abstract: Temperature changes, infrared (IR) images, and heat propagation kinetics of laser irradiated hair fibers and live follicles were measured using a cooled InSb focal plane array detector. Pulsed irradiation of different colored hair follicles under co ...

60. Ultrafast Glimpses at Water and Ice
Published: 3/1/1999
Author: Edwin J Heilweil
Abstract: Recent literature reports of transient infrared hole-burning and spectroscopic measurements on water and ice are critically reviewed. Dynamical measurements on the femtosecond and picosecond timescales show anomalous vibrational relaxation temperatu ...
