luminescence quantum yield ol hnniiiol in dimethyl sulfoxide, initi- 

 ated ^vith tertiary butoxide, give values ot the order of 0.1. This be- 

 gins to look promising, in that if conditions can be found under which 

 the quantum yields in organic solutions can be increased by a factor 

 of only 2 or ?> it may be j)ossiblc to correlate the chemical analysis 

 directly with the chemilumincsccnce quantum yield and to establish 

 once and for all the nature of the excited molecule in chemilumines- 

 cence.
