in order to represent the potential energy function over the whole range of r, many potentialenergy functions have been proposed. in the present paper, we employ many potential energyfunctions, to use numerov method for solving the nuclear schrödinger equation for the ifmolecule, as an example of a heteronuclear diatomic molecules. then we determine thespectroscopic constants eω , e e x ω , e b...

molecular understanding of three-dimensional (3d) peptide: mhc models require both basic knowledge of computational modeling and skilled visual perception, which are not possessed by all students. the present model aims to simulate mhc molecular structure with the hands and make a profound impression on the students.

Molecular gas plays an important role in the structure of planetary nebulae: it is a major component of the equatorial tori of bipolar nebulae, it forms the cores of globules and related mircostructures, and is the likely origin of multiple arcs. It is also a key component during the early stages of formation where interactions with outflows or jets provide an important shaping mechanism.

I. Carbohydrates Carbohydrates are also called saccharides, which is derived from the Greek word sakcharon meaning sugar. The simplest carbohydrates are called monosaccharides, and the biologically important monosaccharides contain from 3 to 7 carbon atoms. The monosaccharides with 5 carbons (the pentoses) and with 6 carbons (the hexoses) may take on different configurations in an aqueous solut...

Electronic structure is the state of motion of electrons in an electrostatic field created by stationary nuclei. The term encompass both the wave functions of the electrons and the energies associated with them.
