Dear QE users, I am currently performing XAS calculation of N-K edge on NH2CH3 and I obtained two peaks following J. Phys.: Cond. Matter.,21 (2009) 104204-1-6. I believe one peak originates from the N-H bond, while the other arises from N-C bond. To further investigate, I also calculated XAS spectra for NH3, NH(CH3)2, and N(CH3)3. [cid:image001.png@01DB8F67.47B2DF70] The peak around 420eV, observed in all molecules except NH3, appears to be consistent, suggesting it is related to the N-C bond. However, the peak around 411 eV differs notably from that in NH3, raising question: What could account for this discrepancy ? or am I misunderstanding the results ?
I would greatly appreciate any advice or guidance on this matter. Thank you very much for your time and assistance. Best Regards, Takahisa Ishiyama
