The paper presents IR spectroscopic data and theoretical frequency calculations, in the C–H and N–H stretch region, on jet-cooled formamide molecules and dimers. By using dipolebound or quadrupole-bound anion formation, one is able to monitor IR absorption in the neutral beam on mass-selected species. For isolated formamide, resonant IR excitation leads to autodetachment of the excess electron ...

This article introduces novel hybrid correlation filter for multimodal face recognition in IR and visible spectrum. In the proposed approach, wavelet based image fusion is used to fuse the face images of a person in visible and IR spectrum. Obtained fused images are then used to synthesize HMACE (Hybrid Minimum Average Correlation Energy) and HMACH (Hybrid Maximum Average Correlation Height) fi...

The 3–20 mm IR thermal emission spectrum of comet Hale-Bopp (C/1995 O1) at a heliocentric distance of AU has been calculated using fluffy aggregates of silicate core–organic refractory mantle interstellar r 5 1.15 h dust as the comet dust model. The principal dust properties, similar to those obtained for other comets, provide good fits to the observation. Our results are significantly differen...

The vibronic spectrum of laser desorbed and jet cooled guanine consists of bands from three different tautomers of guanine as revealed by UV–UV and IR–UV double resonance spectroscopy. 1-methylguanine, in which the Keto–Enol tautomerism is blocked, shows hole burning spectra from the 9H-and 7H-Keto form. A comparison of the vibronic pattern of the different tautomers demonstrates that the vibro...

We present a Spitzer/IRS low-resolution mid-infrared spectrum (5−14 μm) of the luminous transient discovered in the nearby galaxy NGC 300 in May 2008. This transient had peak luminosityMV ≃ −13, showed an optical spectrum dominated by relatively narrow Balmer and Ca II lines in emission, and its progenitor was identified in pre-explosion images as a dust-enshrouded ∼ 10 M⊙ star, characteristics...

The secretory proteins of Chironomus tentans larvae, which are used to construct underwater feeding and pupation tubes, assemble into complexes in vitro. Members of a family of 1000 kDa proteins, the spIs, appear to form the fibrous backbone of the assembled complexes. The spIs consist of a core of tandemly repeating units of 60 to 90 amino acids that can be subdivided into two regions: the sub...

Infrared Spectrophotometry (IR) is now widely used to determine crystalline silica in industrial dust samples. Though the IR method has many advantages when dealing with respirable dust samples, some serious analytical errors are often caused by interference minerals contamination. These minerals have a characteristic absorption band corresponding in position to the analytical peak for crystall...

We have obtained room-temperature transient infrared difference spectra of the M412 photoproduct of bacteriorhodopsin (bR) by using a "rapid-sweep" Fourier-transform infrared (FT-IR) technique that permits the collection of an entire spectrum (extending from 1000 to 2000 cm-1 with 8-cm-1 resolution) in 5 ms. These spectra exhibit less than 10(-4) absorbance unit of noise, even utilizing wet sam...
