Measuring conditions of 1H NMR
1H NMR was measured with a JEOL FX-90Q (89.56 MHz), a JEOL GX-400 (399.65 MHz), or a JEOL AL-400 (399.65 MHz). The measuring conditions for the most of the spectra were as follows: flip angle of 22.5-30.0 degrees, pulse repetition time of 30s. (More information can be obtain from their website)
Measuring conditions of 13C NMR
13C NMR was measured with a NEVA NV-14 (15.087 MHz), a JEOL FX-90Q (22.530 MHz), a Varian XL-100 (25.160 MHz), a Bruker AC-200 (50.323 MHz), a JEOL FX-200 (50.183 MHz), a JEOL GX-400 (100.535 MHz) or a JEOL AL-400 (100.40 MHz). The measuring conditions for the most of the spectra were as follows: a pulse flip angle of 22.5 - 45 degrees, a pulse repetition time of 4-7 seconds, and a resolution of 0.025-0.045 ppm.

Spectral Database for Organic Compounds SDBS an ideal place to obtain most of standard Fourier transform infrared spectroscopy spectrum for your analysis purposes. It is provide by National Institute of Advanced Industrial Science and Technology (AIST), Japan. The FTIR section managed by S.Kinugasa, K.Tanabe and T.Tamura
All the IR spectra were measured and indexed in the website was obtained using a Nicolet 170SX or a JASCO FT/IR-410. The spectral resolution for the Nicolet 170SX was 0.25 cm-1, and the spectral data were stored in the database at intervals of 0.5 cm-1 at 4000-2000 cm-1, and of 0.25 cm-1 at 2000-400 cm-1. On the other hand, the spectral resolution and the interval were 0.5 cm-1 for the JASCO FT/IR-410. Liquid samples were measured with liquid film method, and solid samples were measured by using KBr disc and Nujol paste methods.
You can access the database through this link: Database

Every discipline has wide spectrum of explanations for the question "What is it?".Chemical Engineering, due to its wide range of applications and interest, is described with extensive approaches and definitions.
Famous open encyclopedia, Wikipedia suggests "Chemical engineering is the branch of engineering that deals with physical science (e.g., chemistry and physics), and life sciences (e.g., biology, microbiology and biochemistry) with mathematics and economics, to the process of converting raw materials or chemicals into more useful or valuable forms"
We thought of building a platform to everyone in Chemical Engineering field to give explanation to question "What is Chemical Engineering? with their extensive experiences in the industry or academia.
Please publish your explanation as a comment to this article.
