C60: Buckminsterfullerene
During experiments aimed at understanding the mechanisms by which long-chain carbon molecules are formed in interstellar space and circumstellar shells1, graphite has been vaporized by laserExpand
Quartz-enhanced photoacoustic spectroscopy.
A new approach to detecting a weak photoacoustic signal in a gas medium is described. Instead of a gas-filled resonant acoustic cavity, the sound energy is accumulated in a high- Q crystal element.Expand
Microwave Spectrum, Barrier to Internal Rotation, and Structure of Methyl Formate
Rotational constants have been assigned to the following isotopic species of methyl formate by investigation of their microwave spectra: HCOOCH3, DCOOCH3, HCOOCH2D, HCOOCD3, HC13OOCH3, HCOOC13H3,Expand
Spectroscopic detection of biological NO with a quantum cascade laser
Abstract.Two configurations of a continuous wave quantum cascade distributed feedback laser-based gas sensor for the detection of NO at a parts per billion (ppb) concentration level, typical ofExpand
The formation of long carbon chain molecules during laser vaporization of graphite
Graphite is laser vaporized into a He carrier gas containing various simple molecules such as H/sub 2/, H/sub 2/O, NH/sub 3/, and CH/sub 3/CN, supersonically expanded, and skimmed into a molecularExpand
Lanthanum complexes of spheroidal carbon shells
Laser vaporization of graphite in a high-pressure supersonic nozzle produced a remarkable stable C60 molecule in high yield with striking and exciting new properties. Specifically it was found thatExpand
Widely tunable mode-hop free external cavity quantum cascade laser for high resolution spectroscopic applications
An external cavity (EC) quantum cascade laser (QCL) configuration with the thermoelectrically cooled gain medium fabricated using a bound-to-continuum design and operating in continuous wave at ∼5.2Expand
Reactivity of large carbon clusters: spheroidal carbon shells and their possible relevance to the formation and morphology of soot
The reactivity of bare carbon clusters produced by laser vaporization has been studied by a fast-flow gas-phase reactor followed by F/sub 2/ excimer laser ionization and time-of-flight mass analysis.Expand
