Preparation and thermal decomposition of solid-state cinnamates of lighter trivalent lanthanides
(2000-01-01)
Some new compounds of cinnamic acid with lighter trivalent lanthanides were prepared in the solid state. The compounds have general formula ML3·H2O, where L is cinnamate (C6H5-CH=CH-COO-) and M is La, Ce, Pr, Nd or Sm. ...

Methanol laser line assignments: evidence of four-level laser systems
(1998-03-01)
The Ritz computer program, developed for facilitating the assignment of molecular Fourier transform absorption spectra and described in a previous work, determines the energy level values involved in the assigned transitions ...

Fourier transform-infrared photoacoustic spectroscopy applied in fish scales to access environmental integrity: A case study of Astyanax altiparanae species
(Elsevier B.V., 2015-09-01)
Fish scales have been used to differentiate fish species and to give information on water pollution, besides others different purposes. In the present work, we are proposing, for the first time to our knowledge, to available ...
Upconversion of infrared-to-visible light in Pr3+-Yb3+ codoped fluoroindate glass
(1998-08-01)
Bright fluorescence in the visible range has been observed in Pr3+-Yb3+ doped fluoroindate glass under infrared diode laser irradiation. The mechanism which contributes for the upconversion emission is identified and the ...

On the nu SiO infrared absorption of polysiloxane films
(ELSEVIER SCIENCE SALAUSANNE, 2013-08-02)
The infrared absorption of polysiloxanes involves a strong band at around 1050 cm(-1), attributed to the antisymmetric vibration of siloxane bridges. The splitting of this band into two components is generally attributed ...
