Megjegyzések Evaluated isotopic composition is for most but not all commercial samples. A # jelölésű értékek nem kizárólag kísérleti adatokból származnak, ezeknél rendszeres tendenciákat is figyelembe vettek. A gyenge asszignációs argumentumú spineket zárójelben jelöltük. A bizonytalanságokat rövid formában – a megfelelő utolsó számjegy után zárójelben – adjuk meg. A bizonytalanság értéke egy standard deviációnak felel meg, leszámítva a IUPAC által megadott izotóp-összetételt és standard atomtömeget, melyeknél kiterjesztett bizonytalanságot használunk.
