Exploration of the potential acting on an electron within diatomic molecules

The potential acting on an electron within a molecule (PAEM) is formulated, and then calculated using the ab initio MELD program plus a separate calculation program in the RHF molecular orbital theory, finally the three-dimensional graphs of the potentials have been drawn. We have systematically investigated this kind of the potentials for a series of the diatomic molecules, such as HF, HCl, HBr, LiF, LiCl, and so on. The three-dimensional graph can clearly display the variation of the potential felt by an electron within a molecule and get a deeper understanding of the electronic motion and chemical bonding within a molecule.

Application of Acid Dyestuffs with Different Molecule Structure in Combined Dyeing and Finishing of Cotton Fabric

Simultaneous dyeing and durable press finishing of cotton fabrics with acid dyes bearing the different molecule structure and durable press finishing agent （DP agent abbr. ） based on modified DMDHEU were investigated by using the pad-dry-cure process. Some factors affecting the process, such as structure of acid dyes, DP agent, catalysts and curing temperature were discussed. The dyed and finished fabrics were evaluated with respect to color strength, fixation, crease recovery angle, breaking strength and fastness properties. The results indicate that structure of acid dyes has a striking effect on the color strength of dyed and finished cotton fabric. The color strength and dry crease recovery angle of dyed and finished cotton fabric increases, whereas breaking strength decreases with increasing concentration of DP agent. It is necessary for ammonium nitrate to serve as catalyst. It is found that relatively satisfactory properties of dyed and finished cotton fabric can be obtained with appropriate adjustment of treating conditions.
