DNPFred,

@artlej @nmrchat @chemistry never tried. I thought that was only developed for liquid state spectra. Wrong?

A simple way of increasing the signal-to-noise ratio for the isotopic signals in solid-state MAS NMR spectra by adding spinning side band intensity http://u-of-o-nmr-facility.blogspot.com/2007/11/increasing-signal-to-noise-ratio-in_19.html?m=1 @nmrchat @chemistry

Right #Fediverse, do your thing:

I’m looking for a good #RSS reader. It needs to be cross-platform — at least iOS and Windows, but ideally also Linux. Not opposed to self-hosting or web apps. Should support notifications. Browser extensions would be welcomed. Privacy preserving and open source a bonus.

🚀 #boosts for reach appreciated.

DNPFred,

@danielcolquitt goodish: netvibes as a website.
