The 1H- and 13C-NMR spectra of the trimethyl (1-indenyl) carbon (IV) compound were measured. Assignments of the chemical shifts for 1H and 13C in this compound were obtained by means of hydrogen-hydrogen nuclear Overhauser effect spectroscopy (H-H NOESY), hydrogen-hydrogen correlation spectroscopy (H-H COSY) and carbon-hydrogen correlation spectroscopy (C-H COSY). The 13C chemical shifts of the methyl and C1 carbons were correlated with the electronegativity of the central elements: C, Si, Ge and Sn, of the (CH3)3C(C9H7), (CH3)3Si(C9H7), (CH3)3Ge(C9H7) and (n-C4H9)3Sn(C9H7) compounds.
