We present the complete intermolecular dynamical spectrum of liquid water, by merging the data sets from femtosecond nonlinear‐optical polarization spectroscopy with the depolarized, Bose–Einstein corrected Raman spectrum to cover the ... EWC Jr,YJ Chang,YC Chu,... - 《Journal of Chemical Physics...
We report the detection of water absorption features in the dayside spectrum of the first-known hot Jupiter, 51 Peg b, confirming the star-planet system to be a double-lined spectroscopic binary. We used high-resolution (R~100,000), 3.2 micron spectra taken with CRIRES/VLT to trace the ra...
2). The resultant IR spectrum represents molecular absorption and transmission; the molecules absorb specific frequencies characteristic of their structures. As a result, each sample has a molecular fingerprint, and no two molecular structures create the same IR spectrum. Therefore, IR spectroscopy is ...

52Citations 4Altmetric Metrics Abstract Near infrared spectroscopy (NIRS) has been successfully used for non-invasive diagnosis of diseases and abnormalities where water spectral patterns are found to play an important role. The present study investigates water absorbance patterns indicative of estrus in...
The algorithm has been applied to MODIS brightness temperatures in bands 31 and 32 which are similar to those of the IR camera. The temperatures retrieved by the algorithm are in a very good agreement with the cloud top temperatures given by MODIS. 展开 ...
These results were interpreted as indication that (1) an extended hydrogen bonding network connects D1–E65, –E329 and D2–E312 and an as yet unidentified carboxylate residue that is responsible for this negative 1747 cm− 1 band in the WT difference spectrum and (2) disruption of this ...
In this work, we perform Fourier transform IR spectroscopy experiments of liquid light, semi-heavy, and heavy water; we analyze the data obtained with a model of the dynamical structure of liquid water, to elucidate the elusive ionic contributions to its IR spectrum. In comparison with previous...
calculation of the infrared (IR) spectra of complex systems, which combines the fragment-based Coupled Cluster method and anharmonic vibrational quasi-degenerate perturbation theory, and demonstrate its accuracy towards the complete and accurate assignment of the IR spectrum of the H+(H2O)21 cluster....
