The titled azuleno-annulenone was synthesized and in strong acid its protonated cationic species was generated, which is the first 18-pi electron diatropic condensed bridged annulene as shown in its 'H-NMR spectrum. Although the syntheses and properties of the condensed 18-pi electron systems such
## Abstract ^1^H and ^13^C NMR spectra of several substituted carbazoles (Series 1, 2, 3, 4 and 5) were measured. Substituent chemical shifts (SCS's) and Lynch correlations of ^1^H and ^13^C nuclei were calculated and the substituent effect on the NMR phenomena was determined. Atomic charge densiti
