Different Molecular Weight

Water-soluble phenolic resin was prepared using sodium hydroxide and ammonia as catalysts. The molecular structure of water-soluble phenolic with different molecular weight was studied by infrared spectrum and the mechanism was discussed. The results show that addition reaction and polycondensation synchronize in the reaction process, while addition reaction dominates in the early stage while polycondensation dominates in the later stage.

Sulphur Trioxide

The rotational fine structure of several parallel and perpendicular type bands of sulphur trioxide, an oblate symmetric top, has been partially resolved and analysed. A more convincing assignment of the molecular vibration frequencies has been made than that based upon earlier measurements of the infrared and Ram an spectra. Rotational constants and Coriolis coupling coefficients have been derived, and a more accurate value of the S ═ O bond length has been obtained (1.41 ± 0.01 Å) than that previously assumed on the basis of electron diffraction data. Some vibrational-rotational interactions which affect the appearance of certain bands have been explained.
