Context :

Aims : We analyze individual pulses detected from RRAT J1819 - 1458 .

Methods : From April 2007 to April 2010 , we carried out observations using the Nanshan 25-m radio telescope of Urumqi Observatory at a central frequency of 1541.25 MHz .

Results : We obtain a dispersion measure DM = 195.7 \pm 0.3 pc cm ^ { -3 } by analyzing all the 423 detected bursts .
The tri-band pattern of arrival time residuals is confirmed by a single pulse timing analysis .
Twenty-seven bimodal bursts located in the middle residual band are detected , and , profiles of two typical bimodal bursts and two individual single-peak pulses are presented .
We determine the statistical properties of SNR and W _ { 50 } of bursts in different residual bands .
The W _ { 50 } variation with SNR shows that the shapes of bursts are quite different from each other .
The cumulative probability distribution of intensity for a possible power law with index \alpha = 1.6 \pm 0.2 is inferred from the number of those bursts with SNR \geq 6 and high intensities .

Conclusions :
