According to the characteristic of teaching medicinal organic chemistry,it is helpful to discuss and advocate the application of ChemOffice software in teaching Medicinal Organic Chemistry so as to visualize the class teaching and enhance the efficiency of teaching.

In order to urge students majoring in medicine to know the basic knowledge of organic chemistry experiment in less lessons, enhance their abilities of self-study and train their abilities to think and solve problems, we tried the "PBL teaching method" flexibly during the experimental course teaching of "Medical Organic Chemistry". The result was better than usual.

Objective To investigate the application of of Gaussian 09/GuassView 5.0 in spectra teaching in Analytical Chemistry.Method Undergraduates of Pharmaceutical Science in 2014 grade of Kunming Medical University were selected to teach with a method with the help of Gaussian 09/GuassView 5.0 soft.Calculations of UV spectra,IR spectra and NMR spectra of compounds were introduced to make better understanding in the learning of relative knowledge points.The teaching effect was evaluated by the comparison of theoretical exam results of 2013 grade which didn't use soft.Result The theoretical test results showed that the scoring averages of the 2014 grade in UV,IR and NMR spectra were significantly higher than that in 2013 grade (P＜0.05).Conclusion Gaussian 09/GuassView 5.0 can visualize the nonobjective knowledge,and imporve the students' interesting,thus improving the efficiency of teaching and learning.
