Terahertz study of 1,3,5-trinitro-s-triazine by time-domain and Fourier transform infrared spectroscopy
Huang, F; Schulkin, B; Altan, Hakan; Federici, JF; Gary, D; Barat, R; Zimdars, D; Chen, M; Tanner, DB (2004-12-06)
This letter describes the use of THz time-domain spectroscopy (TDS) applied in transmission to the secondary explosive 1,3,5 trinitro-s-triazine. Samples were also subjected to Fourier transform infrared spectroscopy over the same range for comparison. A detailed spectroscopy study is presented. General agreement between results from both methods confirms the absorption features found. A comparison study with computer molecular simulations shows that THz-TDS is sensitive to collective modes or vibrational m...
Hydride generation and preconcentration of bismuth on a single-drop followed by determination using electrothermal atomic absorption spectrometry
Dügencili, Başak; Ataman, Osman Yavuz; Department of Chemistry (2015)
A novel method for determination of bismuth is proposed where the analyte is converted to its hydride form, BiH3, followed by head space preconcentration on a single aqueous drop; final detection was done using electrothermal atomic absorption spectrometry (ETAAS). The preconcentration step was named as headspace single-drop microextraction (HS-SDME). Experimental parameters for hydride generation using both continuous flow and batch technique, ETAAS and finally HS-SDME were optimized. For HS-SDME, Pd, Ni, ...
Applications in broadband THz spectroscopy towards material studies
Türkşen, Zeynep; Altan, Hakan; Department of Physics (2011)
The purpose of this work was to construct and analyze a THz time domain spectroscopy (THz-TDS) system by using a nanojoule energy per pulse ultrafast laser (non-amplified ultrafast laser or oscillator) source and a non-linear optical generation method for THz generation. First a THz-TDS system, which uses photoconductive antenna (PCA) method for THz generation, was built to understand the working principles of these types of systems. This THz-TDS system which used PCA for generation and a 2mm thick <110> Zn...
Optical characterization of silicon based hydrogenated amorphous thin films by un-visible and infrared measurements
Kılıç, İlker; Katırcıoğlu, Bayram; Department of Physics (2006)
Various carbon content hydrogenated amorphous silicon carbide (a-Si1ŁxCx:H) and hydrogenated amorphous silicon (a-Si:H) thin films have been deposited on various substrates by using plasma enhanced chemical vapour deposition (PECVD) technique. Transmission spectra of these films have been determined within UV-Visible region and the obtained data were analysed to find related physical constants such as; refractive indices, thicknesses, etc. Fourier transform infrared (FT-IR) spectrometry technique has been u...
