The attachment is a heated gas cell with a syringe injector for liquid samples on its body as well as two gas taps for cleaning the attachment after registering the spectrum by purging it with an inert gas. The attachment is designed for quantitative studies using the IR spectroscopy method. ...
only suitable for hydrocarbon-based fires.The UV/IR flame detector senses radiant energy in the short wave section of both the ultraviolet and infrared portions of the electromagnetic spectrum. The signals from both sensors are analyzed for frequency, intensity and duration.Simultaneous detection of ...
t-BuLi was used as an initiator in order to simplify the analysis of 1H NMR spectrum of fac-Ir(ppy)3 end-functionalized PDAS) and the subsequent addition of fac-Ir(ppy)2(vppy) to PDASLi in toluene ([fac-Ir(ppy)2(vppy)]0/[PDASLi]0 molar ratio ¼ 1.00/1.00, 2.00/1.00 and 3....
So far, the NIR region of crystalline melamine has not been studied by quantum mechanical calculations, while the investigations of its IR spectra have remained limited. In the present work, we employed fully anharmonic calculation of the NIR spectrum of melamine based on finite models, and also...
2.1. Vibrational Spectra of C. incanus Material The average vibrational spectra of the studied C. incanus samples recorded using the three spectroscopic techniques are shown in Figure 1. In the ATR spectrum of plant material, most characteristic signals can be attributed to the presence of polysac...

To clarify why the molecular distribution became more stable, we further explored the change of the bottom ZnO and Ir/IrOxwith removing the BHJ films. Comparing with theO 1 score-level XPS spectrum of the fresh ZnO film, the ratio of O-vacancy increases in the aged ZnO film (Fig.5aand...
