摘要: The infinite polyacene (C$\_4$H$\_2$)$_\infty$ has been studied by methods similar to those previously applied the polyene. Whereas in latter most stable configuration is one which C-C bonds are alternately long and short, it found that external all have same length configuration, being slightly shorter than cross bonds. reasons for this examined.
