TL;DR: In this article, the effects of ion-beam bombardment on the physical and chemical properties of poly(allyl diglycol carbonate) (CR-39) polymer have been investigated.
Abstract: The effects of ion-beam bombardment on the physical and chemical properties of poly(allyl diglycol carbonate) (CR-39) polymer have been investigated CR-39 samples were bombarded with 320 keV Ar and 130 keV He ions at fluences ranging from 1 × 1013 to 2 × 1016 ions/cm2 The nature and extent of radiation damage induced were studied by UV–VIS spectrometry, Fourier-transform infrared (FTIR) spectroscopy, X-ray diffraction (XRD) analysis, as well as Vickers' hardness measurements In addition, the effect of ion fluence on the wetting properties of ion-beam bombarded CR-39 polymer was determined by measuring the contact angle for distilled water UV–VIS spectra of bombarded samples reveal that the optical band gap decreases with increasing ion fluence for both Ar and He ions In the FTIR spectra, changes in the intensity of the bands on irradiation relative to pristine samples occurred with the appearance of new bands XRD analyses showed that the degree of ordering of the CR-39 polymer is dependent on the io

TL;DR: In this paper, a small rotational perturbation has been found in the 5Δi ground state of FeO. This occurs in the v = 2 level of the Ω = 2 substate, and only one Λ-boudling component of one rotational level is affected.

TL;DR: In this article, the gaseous MgH2 molecule was discovered in an electrical discharge inside a high temperature furnace and the vibration-rotation emission spectrum was recorded with a Fourier transform spectrometer and the antisymmetric stretching mode (ν3) was detected near 1589 cm−1.
Abstract: The gaseous MgH2 molecule has been discovered in an electrical discharge inside a high temperature furnace. The vibration–rotation emission spectrum of 24MgH2 was recorded with a Fourier transform spectrometer and the antisymmetric stretching mode (ν3) was detected near 1589 cm−1. In addition, three hot bands involving ν2 and ν3 were found and rotationally analyzed. The MgH2 molecule has a linear structure with an R0 Mg–H bond distance of 1.703 327(3) A.
