Exploring the use of Generalized Indirect Covariance to reconstruct pure shift NMR spectra: Current Pros and Cons.
نویسندگان
چکیده
The current Pros and Cons of a processing protocol to generate pure chemical shift NMR spectra using Generalized Indirect Covariance are presented and discussed. The transformation of any standard 2D homonuclear and heteronuclear spectrum to its pure shift counterpart by using a reference DIAG spectrum is described. Reconstructed pure shift NMR spectra of NOESY, HSQC, HSQC-TOCSY and HSQMBC experiments are reported for the target molecule strychnine.

Ultraclean pure shift NMR.
"Pure shift" methods can greatly improve the resolution of proton NMR spectra. However, current pure shift spectra show small periodic artefacts that prevent their use for studying dilute mixture components. A new technique, compatible with all current pure shift methods, is presented that suppresses such sidebands to arbitrary order, allowing ultraclean spectra to be obtained.
متن کاملPros and Cons of Dancing in the Dark: Enhancing EFL learners' oral proficiency in an unplugged learning community
Recent thrust of research has focused on non-conventional classrooms for teaching to EFL learners. Amongst the newly developed models, Unplugged Classroom Model (UCM) is the most debated one as textbooks are aside and the syllabus is based on conversation-driven activities. This study sought to determine the pros and cons of unplugged teaching for enhancing EFL learners' oral proficiency. From ...
متن کاملCompensatory Efforts; A Critique of the Pros and Cons
Compensatory efforts, positive discrimination or reverse discrimination are the terms which nowadays are used in applied ethics for a set of efforts and privileges which are scheduled for compensation of the historical oppressions and discriminations imposed upon some groups and classes in the society. The mentioned oppressions and discriminations may be applied deliberately or inadvertently or...
متن کاملAn Efficient Threshold Verifiable Multi-Secret Sharing Scheme Using Generalized Jacobian of Elliptic Curves
In a (t,n)-threshold secret sharing scheme, a secret s is distributed among n participants such that any group of t or more participants can reconstruct the secret together, but no group of fewer than t participants can do. In this paper, we propose a verifiable (t,n)-threshold multi-secret sharing scheme based on Shao and Cao, and the intractability of the elliptic curve discrete logar...
متن کاملResidual water suppression by indirect covariance NMR.
Residual water solvent signals in 2D NMR experiments adversely affect appearance and subsequent analysis of spectra. A method for water suppression that is based on indirect covariance processing is described. It produces a symmetric spectrum with a water signal that is substantially decreased or completely absent. The method, which can be combined with other water suppression schemes, is demon...
