buckminsterfullerene, c60, is a large molecule consisting of 60 carbon atoms connected to form a hollow sphere. the diameter of a c60 molecule is about 7 x 10–10 m. it has been hypothesized that c60 molecules might be found in clouds of interstellar dust, which often contain interesting chemical compounds. the temperature of an interstellar dust cloud may be very low, around 3 k. suppose you are planning to try to detect the presence of c60 in such a cold dust cloud by detecting photons emitted when molecules undergo transitions from one rotational energy state to another. approximately, what is the highest-numbered rotational level from which you would expect to observe emissions? rotational levels are l= 0,1,2,3,.

Diatomic Gas

Molecule, is a collection of two or more atoms together (which constitute the smallest observable unit) into a pure material. There are some ways to represent the structure of a molecule. Factor symbols represent atoms in Lewis structures, and dots represent electrons that accompany them. A pair of mutual electrons (covalent bond) may be represented by a single dash. The ball-and-stick model depicts the spatial structure of the atoms better.
