[edit] Precursor-Product Relationship
| About the PP Table (行列表示について) | |
|---|---|
| The matrix is viewed columnwise. The topmost precursor ion in bold face produces the product ions beneath it.
Each formula in matrix cells corresponds to the neutral loss. Blackout cells indicate products that cannot be derived, and orange cells indicate a structurally plausible link produced by cleaving a single chemical bond (in cases of ring-opening, two bonds). |
行列は列方向に見ます。最上段太字の前駆イオン(precursor ion)が直下の生成イオン群(product ions)になると解釈します。
行列要素に書かれている組成式はニュートラルロスです。黒は前駆イオンから生成しえない関係、オレンジは分子構造における共有結合1本の切断（開環の場合は2本）で生じる関係を意味します。 |
