The crystal field absorption spectra in the near infrared to visible regions of CsCoCl3·2H2O were investigated. All of the absorption bands were well assiged by taking the crystal field and Racah parameters as Dq=720 cm−1, B=920 cm−1 and C=4320 cm−1, respectively. In the spin forbidden transition 4T1(4F)→2T1(2P) the exciton line and its magnon sideband were observed. The one-dimensionality of magnetic properties is reflected in the temperature dependence of the peak energy and the integrated intensity of the magnon sideband.
