Homonuclear molecule
Homonuclear molecules, or homonuclear species, are molecules composed of only one element. Ozone (O3) is a common triatomic homonuclear molecule. Homonuclear tetratomic molecules include arsenic (As4) and phosphorus (P4). wikipedia.org

单质
单质在物理学上称为同核分子(homonuclear molecule),特指仅由一种元素组成的分子,所含原子可为不同数目,例如O2与O3。一种元素所能形成的同核分子的大小,取决于元素的性质;有些元素可形成不止一种尺寸的同核分子。 wikipedia.org

Sesquiterpenes from Celastrus vulcanicola as photosynthetic inhibitors ...
Three new sesquiterpenoids (1- 3) with a dihydro-beta-agarofuran skeleton were isolated from Celastrus vulcanicola. Their structures were elucidated on the basis of spectroscopic analysis, including homonuclear and heteronuclear correlation NMR experiments (COSY, ROESY, HSQC, and HMBC), and the absolute configurations were determined by circular dichroism and chemical correlations.
