Lithocene
WebTime period: mid Lithocene to early Nyctocene (75 million years to 85 million years in the future). Information: at only around the size of a turkey, the Hippobird doesn’t quite live up to its namesake’s massive bulk. However, it does live near large bodies of water across Antarctica, where it feeds on lakeside plants as well as small animals. Web12 mei 2015 · Takuya Kuwabara, Masaichi Saito.

Web1 aug. 1997 · Ab initio and density functional theory (DFT) calculations using the GAUSSIAN 94 program have been performed to investigate the molecular structure of the lithocene anion at the 3–21G, 6–31G, 6–31 + G, 6–31G ∗, and 6–31G ∗∗ basis sets. This anion is found to be most stable at the D 5d symmetry. The results show that DFT calculations at … WebThe Simplest Metallocene Sandwich: the Lithocene Anion.
