How to Read NMR Spectra of Organic Compounds from Chapter 2/ Lesson 2 27K This lesson describes how to read and interpret proton NMR spectra of organic compounds, including peak splitting, the meaning of chemical shift due to deshielding, as well as peak integration. ...
Mass Spectrometry is a technique used in determining the molecular weight and molecular formula of an organic compound. In this method, the sample is ionized and the resulting ions are deflected based on their mass-to-charge ratios (m/z)....

Comparing to a generic two-state model, our models can distinguish class I from class II MHCs and correlate their structural parameters with the TCR/pMHC’s potency to trigger T cell activation. The models are tested by mutagenesis using an MHC and a TCR mutated to alter conformation changes....

This approach yields a model-free, granular and consistent reckoning of 159 idopyranose solution puckering equilibria studied by NMR and allows us to reproduce the involved 636 NMR vicinal couplings with an overall residual RMS(Jobs-Jcalc) of 0.184 Hz. Our analyses show that for all ring ...
NMR Spectrum: NMR spectrum stands for Nuclear Magnetic Resonance spectrum. It is used for the representation of the number of atoms of carbon and hydrogen that are attached to it. Answer and Explanation:1 We can determine the ratio of the cis and transform of H on the NMR...
2015年10月10日，交通运输部出台了《网络预约出租车汽车经营服务管理暂行办法》。对于之前争论较多的私家车是否能从事专车经营，新规给出的回答是：网络预约出租汽车车辆的使用性质是“出租客运”，这意味着私家车要想从事之前所谓的专车业务，就必须登记为营运车辆。从事出租客运，8年就必须强制报废。而根据规定，小、...
