- Dumb NMR question. Why don't we see splitting from 35Cl or 37Cl in the solvent signal when we run either 1H or 13C NMR? Is it being decoupled as with {1H}13C or does it have something to do with the gyromagnetic ratio or???? #NMR #coupling #decoupling #spectroscopy #chemistry #chemchat #help

- I learnt about the "entropy of the derivative" or delentropy from the paper linked. The idea is that the standard formula for information entropy doesn't distinguish between permutations. The entropy formula −∑p(x)logp(x) depends on p(x) which, absent any extra information about a signal, is estimated by the histogram of that signal.Now, if we do a random permutation of the values of the signal, the histogram doesn't change, so the entropy doesn't change. To find an 'entropy metric' that accounts for that we need to go to the second order, calculating the entropy of the signal derivative.The delentropy is sensitive to […]
- It took a while, but I'm finally back to writing my blog 😎 The first installment for 2026 is an easy introduction to calculating information #entropy for optical spectra (or for any signal, really). In my blog, I focus on #data analysis (#chemometrics, machine learning) applied to optical and near-infrared #spectroscopy Smoothing, or denoising, is one of the most common steps to work with spectroscopy data, and information entropy can be used as a criterion to guide the smoothing process. Better still, the entropy of the derivative of a signal can help with that, because it accounts for the shape […]
