![]() ![]() ![]() The methods used for processing T1 relaxation data in MNova can be applied to other stacked pseudo-2d experiments, like kinetics, diffusion, T2, T1rho, etc. To calculate coupling constants in mestrenova, there are several options. Td, j 10, 3 hz the j value of the doublet is always the distance between the first and second. Numerical value of j is expressed in hz or cps. Also, we use MestreNova for data processing. To calculate coupling constants in mestrenova, there are several options. This video goes through the concept of T1 relaxation, and how to measure T1 for each particular 1H environment. For organic chemists, often the most useful reason for knowing your T1 (longitudinal) relaxation times is so that you can obtain clean integrations - If you have different types of 1H environments, and they have different relaxation properties, it is possible that your 1H integrals may not come out to clean numbers (For example, 2:3 ratio between a CH2 and CH3 group). Typically if one wants quantitative integrations, one must wait at least 5 times the T1 of your slowest relaxing protons. Have you ever wondered why your 1H integrals sometimes don’t come out to clean numbers? T1 (Longitudinal) relaxation is the constant required for your nuclear spins to relax back to equilibrium by a factor of e. 4) T1 Relaxation Measurement – Concept, Data collection, Data Analysis ![]()
