Light rays situated beyond the red end of the visible spectrum generated during combustion and detected by a flame scanner. 

Figure 1 depicts the time resolved spectrum generated by photolysis of 30mtorr of Fe(C0>5 with a KrF excimer laser. As with all transient absorption experiments a major potential problem involves assigning the observed absorptions to specific species. For the...

Modem X-ray and y-ray spectrometers frequently employ semiconductor detectors which produce electrical pulses with sizes proportional to the energies of the incident photons. Using a fast ADC, the signal is digitized and a conventional spectrum generated by a dedicated microcomputer. As many as 8K data points (channels) may be sampled with facilities for perhaps four spectra stored in RAM, together with key information such as calibration data, accumulation time, etc.

For example, consider the following hypothetical reaction scheme in Equation (15) with mixtures of products, each arising from a common chemically activated intermediate that is too short lived to be seen in a spectrum generated by the usual FTICR detection scheme. The chemically activated intermediate can undergo dissociation to yield either distinguishable products, C, D", and E, or the usually invisible product, A", whose formation cannot be readily seen since it is also the reactant ion. After formation of the initial [AB complex, the system may proceed via one or more transition states to different complexes, which themselves may... 

Due to Heisenberg s uncertainty and Pauli s exclusion principles, the properties of a multifermionic system correspond to fermions being grouped into shells and subshells. The shell structure of the one-particle energy spectrum generates so-called shell effects, at different hierarchical levels (nuclei, atoms, molecules, condensed matter) [1-3]. 

The mass spectrum generated with an ICP-MS system is extremely simple (see Figure 1.1). Each elemental isotope appears at a different mass e.g. Al would appear at 27 amu) with a peak intensity directly proportional to the initial concentration of that isotope in the sample solution. A large number of... 

Sinusoidal voltammetry (SV) is an EC detection technique that is very similar to fast-scan cyclic voltammetry, differing only in the use of a large-amplitude sine wave as the excitation waveform and analysis performed in the frequency domain. Selectivity is then improved by using not only the applied potential window but also the frequency spectrum generated [28]. Brazill s group has performed a comparison between both constant potential amperometry and sinusoidal voltammetry [98]. 

In this contribution, we have presented a new mapping procedure from fermion onto boson spaces. This procedure has been tested for a fermion quadrupole-quadrupole interaction in the case of nucleons moving in a single j-orbit. The energy spectrum generated by this interaction within the S-D subspace has been found to compare rather well with the spectrum of an SU(3) 0(6) IBM hamiltonian whose parameters have been obtained with this procedure. 

FIGURE 1 Example of a gel-free-oriented proteomics nano-LC/MS-MS workflow in which bacterial culture proteins digested to tryptic peptides are separated via LC and peptides subsequently analyzed by mass spectrometry. In the process, the spectrometer rapidly cycles every few seconds and examines a size window in which peptide-derived MSI ions are analyzed to define MS/MS (MS2) spectra. The MS/MS (MS2) spectrum generated for each peptide then enters a bioinformatic pipeline for sequence identification, statistical validation, and quantification. 

Figure 14 Methylation analysis using MALDI-TOF MS. The spectra shown here were obtained following a MassCLEAVE assay from a methylated DNA sample (top) and a non-methylated DNA sample (bottom). After bisulphate treatment, the cytosine residues from the Non-methylated DNA are substituted to uracil residues. Following a Cytosine-specific cleavage reaction, the mass spectrum generated from the non-methylated DNA template shows a single peak as expected. The Cytosine residues from the methylated DNA sample are not affected by the bisulfate treatment and the resulting mass spectrum shows expected fragmentation products.
