The rotatory power [[alpha]][.sub.20.sup.D] measured in chloroform solution is -153[degrees], which is consistent with literature data [17-19].
Finally, the Branda team showed that there are several spectral regions where the cyclized and uncyclized compounds have significantly different optical rotatory power, permitting differentiation during read-out.
Physical data in the file include, when available: boiling point, melting point, density, refractive index, optical rotatory power, solubility, crystal properties, and molecular weight.
