Experimental vaues for C-D, C-T?



 Dear Colleagues;
      I would appreciate if anyone with references to experimental determina-
 tions of carbon-deuterium (C-D) and carbon-tritium (C-T) bond lengths and
 strengths/energies in non-cyclic alkanes (e.g., CH3(CH2)nCH2D, CH3(CH2)n-
 CH2T) would send me copies of these citations so that I may check them out.
      I thank all responders in advance for their assistance.
 Sincerely,
 (Dr.) S. Shapiro
