Histidine remained the last aromatic amino acid for which the intrinsic spectroscopic properties and structures were obscure. We measured the UV and IR spectra of protonated histidine, isolated in the gas phase, using photofragmentation cold ion spectrosco ...

Wiley-Blackwell2017

Various vibrational modes present in molecular mixtures of laboratory and atmospheric aerosols give rise to complex Fourier transform infrared (FT-IR) absorption spectra. Such spectra can be chemically informative, but they often require sophisticated algo ...

State-Resolved Methane Dissociation on Pt(111) Studied by Reflection Absorption Infrared Spectroscopy

Rainer Beck, Li Chen, Hirokazu Ueta

The dissociation of methane on Pt(111) was studied using quantum state-resolved methods and reflection absorption infrared spectroscopy (RAIRS), at a surface temperature of 150 K where the nascent reaction products methyl(ads) and H(ads) are stable and acc ...

Quantification of Carboxylic and Carbonyl Functional Groups in Organic Aerosol Infrared Absorbance Spectra

Satoshi Takahama

Atmospheric aerosols are one of the least understood components of the climate system and incur adverse health effects on susceptible populations. Organic aerosols can make up as much as 80% of atmospheric aerosols (Lim and Turpin

Quantum state-resolved gas/surface reaction dynamics probed by reflection absorption infrared spectroscopy

Rainer Beck, Li Chen, Régis Bisson, Hirokazu Ueta

We report the design and characterization of a new molecular-beam/surface-science apparatus for quantum state-resolved studies of gas/surface reaction dynamics combining optical state-specific reactant preparation in a molecular beam by rapid adiabatic pas ...

Theoretical and experimental study of a 30nm metallic slot array

Hans Peter Herzig, Qing Tan, Armando Cosentino

We present the simulation, fabrication, and characterization of a metallic slot grating on a silicon waveguide (30nm slot width for a period of 500nm). According to the simulation, the experimental measured spectrum of the structure exhibits a dip in the n ...
