## Abstract We wish to report here the isolation of methyl __N__โ(__p__โmethoxybenzyl)thiocarbamate, a natural product extracted from __Pentadiplandra brazzena Bailli__, and the synthesis of its homologue, benzyl __N__โ(2โphenylethyl)thiocarbamate. The barrier to internal rotation calculated from a
A simple formula is presented for calculating the approximate partition function of a hindered internal rotational mode of a polyatomic molecule. The formula gives useful accuracy over the whole range from harmonic oscillator to hindered rotator to free rotator
## Communications deconvolved duration is about 300 fs. Considering the dispersion effects in the detection setup, the lengthening compared to the readout pulse is reasonable. The rephasing of the pulse clearly happens only at the programmed delay. It must be emphasized that the three delayed puls
