Satellite Hole Investigation of the Vibrational Modes of 9‐Aminoacridine upon Binding to DNA

Abstract

The spectral features of satellite holes are used to investigate 9-aminoacridine-DNA interactions. The hole depths of the outer ring vibronic modes are reduced more than that of the inner ring vibronic modes.implying that inner ring motion is less perturbed than outer ring motion. As a result, the mode coupling between the inner ring and outer ring is reduced upon binding to DNA. However, similar hole frequency and width of the satellite hole corresponding to the NH 2 mode upon binding to DNA imply that the amino group of 9-aminoacridine sits outside the DNA. 97

The Preparation and Characterization of Magnesium Oxide Whisker

“…9.The precursor consists of MgCO 3 •3H 2 O and MgCO 3 •Mg (OH) 2 •3H 2 O at 40℃ and is converted to 4MgCO 3 •Mg(OH) 2 •3H 2 O reaching to 60℃.The increase of aging temperature accelerate the formation of whiskers, while at the same time, it results in a decomposition of hydrated magnesium carbonate and generating magnesium hydroxide. In addition, the reacting ion has insufficient time for lattice arrangement due to temperature rising, which leads to the transformation in precipitation morphology from whisker to flower-like slice [19,20].

Photoreaction of neutral 9-aminoacridine in glycerol:water glass characterized by satellite holes and antiholes

“…However, the spectral holes in the spectrum of 9AA/PVB film is tentatively ascribed to the change of environmental configurations. The investigation of the distinct satellite holes and antiholes is important for the study of the interactions of 9AA with DNA [29], which is under progress in our laboratory.…”
