[Characteristics on ultraviolet absorption spectrum from difference in temperature and electron transition types of compounds].
The paper states a measuring method about Ultraviolet absorption spectrum from difference in temperature (UVSDT). The UVSDT of chemical compounds have been obtained with UV-240 ultraviolet spectrophotometer. The results show that the characteristic of UVSDT is related to electronic transition type of molecule. The long wave side shifts to long wave, when difference in temperature (delta t) accretes, peak high increases, bathochromic shift augments for UVSDT of n-sigma* electron transition. The UVSDT of n-pi* electron transition has two peak (one positive peak and one negative peak), when delta t accretes, the positive peak up increases, the negative peak down increases. The UVSDT of pi-pi* electron transition become negative peak, when delta t accretes, the negative peak down increases, the location of peak not moves.
