1) nitrogen squaric acid
氮方酸
1.
The structure of nitrogen squaric acid is optimized by the methods of DFT/B3LYP/6-311+G(d,p)、MP2/ 6-311+G(d,p) and MP2(full)/6-311+G(d,p).
采用DFT/B3LYP/6-311+G(d,p)、MP2/6-311+G(d,p)和MP2(full)/6-311+G(d,p)优化了氮方酸的几何构型,计算发现DFT/B3LYP/6-311+G(d,p)方法优化的几何构型较为合理。
3) nitrogenoxosquaric acid
