Zero‐field splittings and splitting parameters of phosphorescent phenanthrene oriented in single crystal biphenyl are reported as functions of guest content in the range 10−6 to 2×10−2 mole fraction guest from measurements at ∼77 K. The dependences, which have been fit to equations of the form y=axb, are attributed to molecular crystal field effects. In addition, EPR absorption linewidths have been measured as a function of guest content and are discussed in terms of spin–spin interactions. The liquid–solid phase behavior of the two component phenanthrene–biphenyl system is also reported.
