Infrared Study on Crystal Formation-Growth Process and Crystal Structure of Maleimide from Gaseous Solution System Including Air or Air/MeOH Mixture as Solvent Gas

Yuki Tsurumura, Toshifumi Yoshidome, Janice B. Rabor, Hidetoshi Miyazaki & Morihide Higo · International Research Journal of Pure and Applied Chemistry · 2013

We investigated crystal formation process and crystal structure on a surface or in a bulk medium in gaseous solution system, using maleimide as solute gas and air or air/MeOH as solvent gas. In the air solvent, some of the gaseous maleimide molecules aggregated to form small crys...

Luminescence Spectral Changes of Solid EuCl3•6H2O Under N, N–Dimethylformamide and Methanol Vapors

Janice B. Rabor, Toshifumi Yoshidome, Tatsuya Mitsushio, Keisuke Yoshida, Brian J. Sarno & Morihide Higo · International Research Journal of Pure and Applied Chemistry · 2013

Luminescence spectral changes of solid EuCl3·6H2O in the presence of N, N–dimethylformamide (DMF) and methanol (MeOH) vapors were studied. Difference spectra and 2 dimensional correlation spectra obtained from luminescence spectra were used to determine base components of the lum...

Micrometer–Range Pattern Formation of Crystal Films from Liquid Thin Films of Maleimide Methanol Solution

Janice B. Rabor, Toshifumi Yoshidome, Keigo Tamaki, Yuki Tsurumura, Brian J. Sarno & Morihide Higo · International Research Journal of Pure and Applied Chemistry · 2012

Crystal films of maleimide were produced from methanol solution liquid thin film climbing a vertical glass substrate. Optical microscopy and infrared (IR) spectroscopy were used to evaluate the crystal films. Maleimide methanol solution produced four banded crystal films with dif...
