## Abstract The ^13^C methylene carbon absorptions of poly(methyl methacrylate) with a random structure were assigned in terms of tetrad sequences using the 2D COSY (^1^Hβ^13^C) NMR spectrum and by comparison with the absorptions of isotacticβrich and syndiotacticβrich poly(methyl methacrylate)s. T

## Abstract The complete ^1^H and ^13^C chemical shift assignments of the 13Ξ±βepimer of estrone methyl ether and of estrone methyl ether itself were carried out, making use of oneβ and twoβdimensional NMR techniques (1D HOHAHA, COSY, NOESY, TOCSY and HSQC). Copyright Β© 2001 John Wiley & Sons, Ltd.
