AI Thread Summary
To zero the NMR spectra of Dimethylacetamide in CDCl3, it's important to identify a reference peak, typically TMS, which is not present in this case. The two smaller peaks near zero may be residual solvent signals, but they should not be used for zeroing. Instead, focus on the larger peaks corresponding to Dimethylacetamide for accurate referencing. If TMS was not added, consider using a known peak from the Dimethylacetamide spectrum for calibration. Proper zeroing is crucial for accurate interpretation of the NMR data.

Homework Statement


I have a spectra of the NMR, I'm just confused on where to `zero' the spectra at?

Homework Equations


The Attempt at a Solution


There are two peaks around zero in the spectra (one is bigger than the other but not by much). Also the two peaks are much much smaller than the peaks I know are Dimethylacetamide. I just don't know where to zero it.

Any help is appreciated

So, you didn't put any TMS in your CDCl3?
 
We used 3% TMA?
 

Thread 'Prove that evolution is constant (Provide at least two arguments to support your position)'

I don't get how to argue it. i can prove: evolution is the ability to adapt, whether it's progression or regression from some point of view, so if evolution is not constant then animal generations couldn`t stay alive for a big amount of time because when climate is changing this generations die. but they dont. so evolution is constant. but its not an argument, right? how to fing arguments when i only prove it.. analytically, i guess it called that (this is indirectly related to biology, im...

Thread 'How to find the pH of a galvanic cell (MIT OCW problem set)'

This is the final problem in this problem set from MIT OCW. Here is what I did to try to solve it The table cited in the problem is below We can easily spot the two redox couples that are in the electrochemical cell we are given. The hydrogen-based electrode has standard potential zero, and the silver-based electrode has standard potential 0.22. Thus, the hydrogen electrode, with the lower potential, is the reducing agent (ie, it is where oxidation happens) and is the anode. Electrons...
