Vapor-Phase Photolysis ofcis-Cyclononene

Vapor-phase synthesis of nanoparticles

An overview of methods for preparing nanoparticles in the vapor phase is given, and recent advances are reviewed. Developments in instrumentation for monitoring vapor-phase synthesis of nanoparticles and in modeling these processes are also included. The most important developments relate to improved control and understanding of nanoparticle aggregation and coalescence during synthesis, and to ...

Gas Phase Far Ultraviolet Photolysis and Radiolysis of Vinyl Chloride

Quantum yie lds of the major products formed in the far ultraviole t photolys is of CH,C DCI (C2 H2 , C, HD , C,HoD, C, H2 D" and 1,3·C, H,D,) have been de termined at 147 nm (8.4 eV), 123.6 nm (10.0 eV), a nd 104.8106.7 nm 01.611.8 eV). The quantum yield of the s tab le vinyl rad icals which can be un· ambiguous ly asc ribed to the primary process (CH2CDCI + hll ~ CH,C D+ CI) is 0.3 a nd 0.05 ...

Peptides and proteins in the vapor phase.

This article provides a review of recent studies of the properties of unsolvated (and partially solvated) peptides and proteins. The methods used to produce vapor-phase peptide and protein ions are described along with some of the techniques used to study them, such as H/D exchange, blackbody infrared radiative dissociation, and ion mobility measurements. Studies of unsolvated peptides and prot...

Vapor Phase Esterification over Sodium Acid Sulfate

Quantitative vapor-phase infrared spectrometry of ammonia.

Reference spectra of ammonia from four sources are compared. Low-resolution spectra (i.e., spectra for which the spectrometer resolution is numerically greater than the full-width at half-height of the rotational lines) were obtained from the Environmental Protection Agency (EPA) web site and from Infrared Analysis, Inc. High-resolution (0.12 cm-1) spectra were obtained from the National Instit...
