摘要:

Phthalocyanines, crown ethers, and crown ether bridged phthalocyanine compounds have recently attracted a great deal of attention because of their interesting properties1–5. The spectroscopic specifications of these molecules have been studied for a long time. However, their structures are not completely elucidated since they have relatively big monomers, and form giant polymers4,6,7. There are many studies on the spectroscopic specifications of phthalocyanines8–10, but one of them which recently appeared in Journal of Chemical Physics may be important as a theoretical reference from now on1. Similarly, the spectroscopic properties of crown ethers have been investigated for about twenty years11,12. Meanwhile, some spectroscopic properties of crown ether bridged phthalocyanine compounds have also investigated previously3–7,13,14

摘要:

The present Raman investigation of anhydrous alloxan and the misnamed alloxan monohydrate suggests that some of the assignments previously made on basis of the IR spectrum of the anhydrous compound must be changed, i.e., the ones related to the NH stretching and ring breathing modes. The hydrogen bonding network in the crystal of the so called alloxan monohydrate, although extensive, is not strong enough to cause substantial frequency shifts in the NH and CO stretching modes.
