Bonds adjacent on rings
WebPolycyclic ring systems in which any two adjacent rings have two, and only two, adjacent atoms in common are said to be ' ortho -fused'. Such ring systems have n common sides and 2 n common atoms. WebThe concept of shielding will be explained shortly. The position on the plot at which the nuclei absorbs is called the chemical shift. Since this has an arbitrary value a standard reference point must be used. The two most common standards are TMS (tetramethylsilane, (Si (CH 3) 4) which has been assigned a chemical shift of zero, and CDCl 3 ...
