  The Martian has shot right up there to be one of my favourite books. Mark Watney is such a believable, funny and smart character, and the book made me feel actually afraid for him when things kept going wrong, made me laugh at all of his wisecracks, and make me root for him to keep going in the face of continuous almost certain of death/5(K). We studied the luminescence of molecular nitrogen nanoclusters containing stabilized nitrogen, oxygen, hydrogen, and deuterium atoms. Optical spectra were observed during the destruction of these ensembles of nanoclusters accompanied by a rapid release of chemical energy stored in the samples. Several interesting features were observed including a broad band near λ ≈ nm, which was Cited by: 4.

2 triplet band emissions on Titan, including the recently observed N 2 VK bands. The model includes interstate cascading and quenching, and uses the Analytical Yield Spectra approach for the cal-culation of electron impact excitation of triplet bands, and is similar to the model used for studying the N 2 triplet emissions on Mars (Jain and Bhardwaj, ).

Recently the Cassini Ultraviolet Imaging Spectrograph (UVIS) has revealed the presence of N 2 Vegard–Kaplan (VK) band A 3 Σ u +-X 1 Σ g + emissions in Titan’s dayglow limb observation.

We present model calculations for the production of various N 2 triplet states (viz., A 3 Σ u +, B 3 Π g, C 3 Π u, E 3 Σ u, W 3 Δ u, and B 3 Σ u) in the upper atmosphere of by: Measurements of relative band intensities for the N 2 Vegard–Kaplan bands with υ′ = 0 are used to find a curve that represents the smooth variation of the electronic transition moment with internuclear separation.

The Vegard–Kaplan bands were observed in the discharge afterglow without appreciable contamination from other N 2 systems.

Spectra of active nitrogen have been photographed under conditions comparable to those used for most studies of reactions of active nitrogen with other molecules. Bands observed were identified as the first positive system of nitrogen and the β- and γ-bands of nitric oxide. No trace of Vegard–Kaplan emission was by: 3.

The Earth's ultraviolet airglow contains fundamental diagnostic information about the state of its upper atmosphere and ionosphere. Our understanding of the excitation and emission processes which are responsible for the airglow has undergone dramatic evolution from the earliest days of space research through the past several years during which a wealth of new information has been published Cited by: The Vegard-Kaplan bands and other systems of neutral nitrogen by George Robinson Taylor, edition, in English The rotational structure of the Vegard-Kaplan bands of N2.

Irradiation of solid nitrogen at 4 K with far-ultraviolet light from a synchrotron caused excitation to the upper state of the Vegard–Kaplan (VK) system; the emission in that system was simultaneously recorded in wavelength region – nm.

This radiation consists of the Vegard–Kaplan bands (, the first positive and the second positive (N 2 (C 3 Π u, v) → N 2 (B 3 Π g, v')) systems of nitrogen.

The most known models of vibrational kinetics of electronically excited states, N 2 (B 3 Π g, v), N 2 (C 3 Π u, v) in the auroral atmosphere are published in [7–9].Cited by:.

In the terrestrial atmosphere emis-sion from Vegard-Kaplan (VK) bands are weak due to e cient quenching by atomic oxygen, but CO 2 is not good at quenching VK bands (Fox and Dalgarno, ; Dreyer et al.,), so the intensity of these band should be appreciable in Martian by:   A common screen for plant antimicrobial compounds consists of separating plant extracts by paper or thin-layer chromatography (PC or TLC), exposing the chromatograms to microbial suspensions (e.g.
