This table is useful for quick qualitative determination of proton spertrum lines by providing 3. tabulation of line positions obtained using tetramethylsilane as an internd reference. The listing has heen kept as simple as possible far this purpose. The proton spectrum lines are arranged aacording to the chemical shift relative to tetramethylsilane and are given in values of r and c. The purpose of this table is to supplement tables available in standard reierences and tu summarise information available in the literature.
