CARS (Coherent Anti-Stokes Raman Scattering) has developed into a powerful tool for studying molecular systems. One of itspossibilities is to derive vibrational and rotational temperatures as well as concentrations of molecules from measurementsof the energy level population differences. A very good ...
Polarized and depolarized CARS band shapes are reported for the 2ν2band of the Fermi resonance diad in room temperature CO2gas at a series of densities. Analysis of the spectra yields vibrational relaxation times and the shift of the band center with density. Comparison of the depolarized spectr...
that emit the least CO2. The lower the emission band, the lower the tax you'll pay and the more environmentally friendly. The label is also a guide to the running costs you can expect for that car over 12,000 miles, this will allow you to compare the running costs of different cars....
For the life-cycle emission comparisons, a database of vehicles was created, which should fairly represent the majority of all commercially available passenger cars, such as Volkswagen Passat, Audi A4, Tesla Model 3, Toyota Mirai, Mercedes-Benz C 300 d, etc. The main goal was to include as...
Volkswagen AG understated emissions of carbon dioxide that it reported to European regulators, presenting the latest legal challenge for the embattled automaker. Volkswagen said yesterday it failed to report accurate greenhouse gas totals for about 800,000 cars sold in Europe and overstated their fuel...
The G-band shift is ~4 cm−1 towards higher frequency, indicating ~4% 12C was present in this sample using Equation 1, to provide evidence tGh-abta(n12dCi)nCthOis2 is directly absorbed from sample, which can be seen the air in the formation of the carbon by the larger FWHM (full...
„Es wird keine weiteren Selbstverpflichtungen mehr geben. Das ist eine schlechte Nachricht für deutsche Premiumhersteller. Die italienischen und französischen Autobauer sind nicht mehr willens, die Deutschen bei den Emissionen ein zweites Mal zu subventionieren“. Mit diesen Äußerungen ...
Abstract Absolute intensities for the Q -branch of the 4nu2 nu1 + nu2(1) (20003-11101) band in CO, have been measured for the first time. Measurements were performed for lines Q10 to Q28, at temperatures ranging from 385 to 426 K, for pressures from 3 to 40 torr, using our long...
consumers have the incentive to switch to cleaner vehicles within the same VED band. This would not happen under the VED, as the tax rate is the same within a band. Our result is the combination of this effect and the loss of tax incentives (disincentives) for very clean (very polluting...
CARS spectra of the ν 1 band of water vapour at room temperature and 2100 K over a large pressure range (200–19 × 10 5 Pa) were studied experimentally... F Grisch,M Pealat - 《Journal of Raman Spectroscopy》 被引量: 21发表: 1994年 Reduction of OH vibrational frequencies in amino ...
