The sample solution of KNO 3 is ejected into the gas phase and the ionic dusters of K + (KNO 3 ) n and NO 3 (KNO 3 ) m are formed and observed by electrospray ionization mass spectrometry (ESIMS). Hie full mass spectra of both the positive ion and the negative ion show that the differences between each peak nearby are all about 101 ( m/z ), which correspond to the molecular weight of KNO 3 . The general formula of the ionic clusters can be assigned as K + (KNO 3 ) n and NO 3 ′‐(KNO 3 ) m. .
