In this paper, we present the first measurements of the vertical distribution of cyanogen ( ##IMG## [http://ej.iop.org/images/1538-3881/160/4/178/ajabafb2ieqn1.gif] {${{\rm{C}}}_{2}{{\rm{N}}}_{2}$} ) in Titan’s lower atmosphere at different latitudes and seasons, using Cassini’s Composite Infrared Spectrometer far-infrared data. We also study the vertical distribution of three other minor species detected in our data: methylacetylene ( ##IMG## [http://ej.iop.org/images/1538-3881/160/4/178/ajabafb2ieqn2.gif] {${{\rm{C}}}_{3}{{\rm{H}}}_{4}$} ), diacetylene ( ##IMG## [http://ej.iop.org/images/1538-3881/160/4/178/ajabafb2ieqn3.gif] {${{\rm{C}}}_{4}{{\rm{H}}}_{2}$} ), and ##IMG## [http://ej.iop.org/images/1538-3881/160/4/178/ajabafb2ieqn4.gif] {${{\rm{H}}}_{2}{\rm{O}}$} , in order to compare them to ##IMG## [http://ej.iop.org/images/1538-3881/160/4/178...] {${{\rm{C}}}_{2}{{\rm{N}}}_{2}$}

泰坦平流层中的C 2 N 2垂直剖面

在本文中，我们提供了对氰化物垂直分布的首次测量（## IMG ## [http://ej.iop.org/images/1538-3881/160/4/178/ajabafb2ieqn1.gif] {$ {{\ rm {C}}} _ {2} {{\ rm {N}}} _ {2} $}）使用卡西尼的复合红外光谱仪远红外数据在不同纬度和季节在泰坦的低层大气中。我们还研究了在我们的数据中检测到的其他三个次要物种的垂直分布：甲基乙炔（## IMG ## [http://ej.iop.org/images/1538-3881/160/4/178/ajabafb2ieqn2.gif] {$ {{\ rm {C}}} _ {3} {{\ rm {H}}} _ {4} $}），二乙炔（## IMG ## [http://ej.iop.org/ images / 1538-3881 / 160/4/178 / ajabafb2ieqn3.gif] {$ {{\ rm {C}}} _ {4} {{\ rm {H}}} _ {2} $}）和＃ ＃IMG ## [http://ej.iop.org/images/1538-3881/160/4/178/ajabafb2ieqn4.gif] {$ {{\ rm {H}}} _ {2} {\ rm { O}} $}，以便将它们与## IMG ## [http://ej.iop.org/images/1538-3881/160/4/178比较。
