【Abstract】 The structural and spectroscopic properties of three spiroindolinonaphthoxazinederivatives in CDCl₃ and CCl₄ were studied by ¹H and ¹³C NMR spectroscopy． Themethods of ¹H-¹、^H-¹³C COSY， relaxation rate seperation and theorietical simulationof the spin systems were used． The results indicate that compounds Ⅰ，Ⅱ and Ⅲ arein the spiro-like conformation in both solvents.更多还原
