aIt looks like solvent peaks shown on NMR. You can use vacuum pump to remove solvent, the temperature is 60 degrees, It may takes 5-6 hours. 它看似在核磁共振显示的溶解的峰顶。 您能使用真空泵去除溶剂,温度是60度,它可以作为5-6个小时。 [translate] ...
NMR Solvent Peaks is a conveniently-searchable version of the ungainly table of NMR data most organic chemists keep a copy of nearby. Instead of searching through the table for a peak near your unidentified peak, just enter your solvent and the peak's multiplicity and location and you'll have...
The quantity of peaks in a signal is directly linked to the quantity of adjacent, distinct protons that are not equivalent (N+1 rule). Examine the splitting pattern to ascertain the number of neighboring protons. A singlet, characterized by a single peak, indicates the absence of nearby ...

After the addition of an optimized amount of the oxidant, H2O2, the spectrum changed its pattern with the characteristic peaks in the range of 380 - 430 nm. This spectroscopic pattern concludes that the complex has been converted into a ruthenium (IV) species, in fact a ruthenium (IV) oxo...

During in-situ GIWAXS measurement of the first five minutes of high temperature annealing, reflections corresponding to6R-PbI2gradually appear, but the intensity and position of these peaks stabilises – along with those of α-FAPbI3– consistent with complete volatilisation of small quantities of ...
