The phrase "absolute spectra" is correct and usable in written English.
It can be used in scientific or technical contexts, particularly in fields like physics or chemistry, to refer to the complete range of wavelengths or frequencies emitted or absorbed by a substance.
Example: "The absolute spectra of the compound were analyzed to determine its electronic transitions."
Alternatives: "complete spectra" or "total spectra".
In this paper, methods of obtaining absolute spectra from the non-acoustically treated Markham wind tunnel at the University of Cambridge are discussed.
Finally, a dipole beamforming vector is used to account for the directivity of the landing gear noise, leading to good agreement between absolute spectra from the differently sized arrays.
The analysis of the absolute spectra obtained for NO-covered Pt(111) and Rh(111) electrodes shows a linear variation of the band center frequency of linearly bonded NO with slopes of 65 and 20cm−1 V−1, respectively.
We have obtained the absolute spectra of H and He by analyzing data collected by a series of annual flights of the Balloon borne Experiment with a Superconducting solenoid Spectrometer payload.
Subsequently, absolute spectra were computed via a fast Fourier transform (FFT) for each segment.
Result *.txt files were exported to a data server with absolute spectra intensities and further processed by the BinBase algorithm [32] for removing inconsistent and noisy spectra.
Third, features that model the shape of the power spectrum as a 1/ f-curve as well as the absolute spectrum in the α range are discriminative.
Otherwise, almost no appreciable changes are seen in the spectral shape of H135A compared to that of the wild type except for differences in the amplitude of the bands in the amide I and II regions (1700 1600 and 1600 1500 cm–1, respectively), where strong absorbance by these bands in the absolute spectrum can compromise the linearity in the difference spectrum.
It is concluded that absolute acceleration spectra, instead of pseudo-acceleration spectra, should be used for EFSDOF oscillators in force-based design of SSI systems.
Figures 10a, b and 11a, b show the absolute acceleration spectra and the relative velocity spectra (damping: 5%) based on the observed foreshock records at JKM with respect to the design response spectrum of the Specifications for Railway Structures (RTRI 2012) and the surface ground conditions at JKM (see Table 3c).
Therefore, here we present comprehensive radiometric analysis of LEDs in terms of absolute emission spectra, radiometric power output, irradiances, radiant efficiencies as well as uncertainties.
