Methane (CD4) - References
| Overview | methane-D4 is an isotopic derivative of methane, abbreviated as CD4. Methane and methane-D4 as one of the most simple organic matter, their molecular spectra have long been experimentally studied, and methane has also been an important example of quantum chemical calculation. |
| Molecular Geometry | with HF/6-31G **,B3LYP/6-31G**,MP2/6-31G * *, the geometry of methane and methane-d4 was fully optimized by MP4/6-31G **and other methods, and the obtained C- H, C- D bond length was 0.1084 nm, and H-C-H bond angle was 109.5 °, it is in good agreement with the experimental results (Table 1). |
| purpose | methane D4 is mainly used as a nuclear magnetic resonance reagent, pharmaceutical and synthetic, photoelectric material modification, laboratory-specific reagents, chemicals, scientific research, testing, etc. |
